Frigoboat Sets the Standard in Marine Refrigeration

With several different compressor models available, Frigoboat is capable of cooling refrigerator boxes of up to 20 cubic feet or freezer boxes up to 10 cubic feet.

The basics of a refrigeration system are a compressor/condenser, an evaporator and a box or area to contain the cold air. Additionally, a controller/thermostat is used to control the system, so it doesn’t just run all the time.


Compressors/Condensers

Frigoboat offers three types of compressors so there’s one for every budget.

  • Air Cooled Compressors
  • Water Cooled Compressors
  • Keel Cooled Compressors

Air Cooled Compressor/Condenser refrigeration systems use a fan to move cooing air through the condenser and provide your boat with cold food storage.

Water Cooled Compressor/Condenser refrigeration systems use an external water pump to move cooing water through the condenser for your boat’s refrigerator/freezer.

Keel Cooled Compressor/Condenser systems use a keel-cooler as the condenser to provide the best most efficient, and quiet, form of marine refrigeration.

Frigoboat Offers Three Evaporator Options

Bendable Flat Plate can be used flat or bent to fit in your refrigerator or freezer box.

The Flat Plate with Stainless Cover (Non-Bendable) is recommended if bending is not required and offers protection from hard object thanks to the steel cover.

Vertical & Horizontal Bin Type Evaporators are a pre-bent plate that forms a small freezer section in the ice box on your boat.

Frigoboat Thermostats

Frigoboat offers Manual Thermostats for refrigerators or freezers and Digital LED Thermostats. The LED thermostats include a display panel that can be mounted conveniently where you can clearly see what your refrigerator/freezer box temperature is at any time.

The Frigoboat Optional Fan Speed Control

Frigoboat’s Merlin II is a small circuit board that plugs onto the controller of your Danfoss BD35 or BD50 compressor to control the compressor speed automagically! The Merlin II includes a green LED that blinks to show at what speed the compressor is running and a red LED that blinks one to five times to tell you where to troubleshoot should your compressor stop for an electrical fault reason.

Merlin II gives you big energy savings while also protecting your system’s electronics and reducing the stress on various components.

The Proper Care & Feeding of your Marine Fuel System

75500MAX Go2marineThe Proper Care & Feeding of your Marine Fuel System

One of the primary needs of your vessel’s internal combustion engine(s) is clean fuel. On many boats, an effective fuel filtration system is often overlooked when the boat is manufactured. With today’s fuel injected gasoline powered boats, fuel quality must be almost pristine to avoid problems with these engines. Contaminated fuel can cause the myriad of electronic sensors on these engines to give all mannerisms of improper signals to the engine’s computers and also give improper diagnostic codes to the mechanic attempting to troubleshoot them. Diesel-powered boats usually have a fuel filter on board, but even those can be upgraded to ensure that contaminant free fuel is getting to the engine.

Purchase Fuel Filters at Go2marine.com

The most common problems usually begin with the introduction of water into the fuel. Water is commonly found in fuel systems and can come from a variety of sources. Condensation, fuel handling and environmental conditions are the main causes of contamination. Humid marine environments will increase the presence of water. Water contaminated fuel can lead to very severe engine damage if it is not detected and treated.

Contaminated fuel contributes to damage caused by oxidation (rusted metal parts) and suspended particles of iron oxide, microbiological growth and sulfuric acid damage, normally seen in diesel fuel. Fuel provides lubrication to the fuel injection system. Water displaces the fuel’s lubricating qualities increasing the chances of premature wear and galling.

Most factory installed filters such as those found in carburetors, fuel pump canisters and engine mounted filters do not have the capability of removing water. For this reason, the addition of a quality fuel filter/water separation unit is absolutely necessary to prevent the causes of engine damage. On most small gasoline powered boats, this can easily be accomplished with the addition of an accessory spin-on style fuel filter/water separation unit. These inexpensive units are commonly available at most marine supply stores and boat dealership parts counters. Be sure to size the system for your engine’s horsepower and fuel flow needs. These filter assemblies are usually very easy to install near the fuel tank in your boat. Always include a couple of replacement filters to add to your boat’s spare parts locker. If you encounter a bad case of water contamination while underway, which is caused by the fuel sloshing around in the tank mixing with the water, you will have the ability to drive the boat home rather than row it if you carry extra filters. This is because the water in the fuel will not pass through the filter and will plug the filter media decreasing the flow of fuel. You will notice this as a marked reduction in engine rpm’s which usually gets worse. Remove the contaminated spin-on filter, put it in a bucket for proper disposal later, and install a fresh filter. When you get back to shore, check into the problem as soon as possible to avoid further damage. When installing a fuel filter/water separator on your boat, be sure to follow United States Coast Guard guidelines for materials used and mounting locations.

An important thing to always remember is DO NOT use automotive fuel system additives or fuel dryers. This is because most of these products contain alcohol which ATTRACTS water into the system, compounding your problems. Always use marine fuel additives.

Diesel fuel systems, though more complex, will benefit greatly with the addition of a properly selected fuel filter/water separation system. Any vessel making long distance or offshore passages will be best served using a duplex system. This system uses two or more filters with a manifold and valve that allows the engine to continue operating on one filter while the other filter is being serviced. Most of these units utilize a vacuum gauge to determine filter efficiency and forewarn you of impending blockage. Vessels not going offshore will be improved with the addition of a properly sized single fuel filter/water separator assembly, but a dual system, though more expensive, provides an excellent margin of safety and reliability.

Most diesel fuel filter/water separator assemblies are sold with 2 micron filters however, the secret to the most effective and efficient fuel filtration is STEP-DOWN filtration. RACOR Filters states in their catalog, “A 30 micron filter (or primary filter) is used to filter raw fuel (or poor quality fuel) before it can be further filtered by finer medias such as a 10 or 2 micron. A 10 micron filter (or secondary and even final) is used to filter fuel which is known to be of very good quality. A 2 micron filter (or final filter) is the finest filtration available and is the last filter used prior to engine ingestion.” In other words, the first filter in line from the fuel tank (primary) should have a larger micron rating than the filter (secondary) located further on down the line or on the engine. The secondary filters are commonly 10 micron rated. If you use a 2 micron primary filter, a larger micron rated secondary filter will be doing absolutely nothing while reducing the overall efficiency of your system. The primary filter should be either a 10 micron or 30 micron rated filter. Keep in mind that using the small micron rated filters will also require more frequent filter changes. Exceptionally high fuel-flow engines, such as Detroit Diesels, should use the largest micron rating as the smaller sizes will restrict fuel flow and will need to be changed more often than necessary. Remember, it is fuel flow, not fuel consumption that determines the correct size of the fuel filter/water separator unit you use. Many engines use a fuel bypass system that routes unused fuel back to the fuel tank after it passes through the filtering system. Additionally, many small diesels are equipped with equally small fuel lift pumps. Using a small micron rated filter increases the load on these small pumps which can lead to premature failure. A properly sized primary filter used in conjunction with the engine mounted secondary filter will provide all the filtration needed to guarantee good fuel quality.

Fuel filter/water separator assemblies are available in both spin-on and drop-in element styles. Gasoline spin-on replacement filters are available almost everywhere. For diesel applications, the drop-in replacement element is considerably less expensive and much easier to find than the spin-on styles if you cruise to remote areas. A good rule of thumb, especially if you have difficulty servicing engine mounted secondary filters, is to change the primary filter twice to every secondary filter change.

It is surprising, but you can routinely find rust, sand and other small particles in your fuel. Sometimes even larger items can be present. Oxidized organic semi-solid contaminants such as carbon, gums and varnishes are the most common causes of plugged fuel filter elements. Efficient fuel filtration devices must be capable of retaining solid particle contaminants while also providing sufficient capacities for the natural organic contaminants found in diesel fuel.

In areas known to have contaminated fuel problems, pre-filters are commonly used. While these aren’t really filters as we normally think of them, they are very effective at removing contaminants and extending filter life. These pre-filters are cleverly designed to trap contaminants and be drained as necessary at regular intervals. Commercial fishing and charter vessels have successfully used these for some time and now, many pleasure boaters are installing them.

Whether you have a gasoline or diesel-powered vessel, the proper care and feeding of your boat and its total fuel system will provide you with many happy and trouble-free hours of boating pleasure.

Are your dock lines good enough?

Father Time and Mother Nature take their toll on dock lines. Are your dock lines good enough? Are they strong enough to withstand the elements? The dock line seen here is good enough, right? It just has a little wear on the outer braid that carries half the line load. The inner braid is up to the job of carrying the other half of the load. Right?

Maybe and maybe not.

If you are constantly on your boat and checking your lines regularly, then you can put off replacing them. On the other hand, your boat may only get visited occasionally over the winter and a line in this condition can degrade rapidly. Remember, the inner braid’s condition may be compromised by the environment and not up to the job of keeping your boat where you left it tied to the dock or mooring buoy.
A set of dock lines is inexpensive insurance for your peace of mind and safety of your boat. Get a new set of dock lines as an easy to keep New Year’s Resolution, rest easy till boating season and get in a winter visit down to the dock to change out the old lines.

It is a real good idea to replace all your dock lines at the same time just like your car headlights. You change them out in sets. Right?

Fire Extinguishers and your Boat

Fire extinguisherNothing causes as much concern for a boater than a fire aboard while underway. Here is what happens in a boat without an automatic engine room extinguisher. Most boat fires start in the confines of the engine room, killing engine and electrical power to the vessel. One or two 2BC extinguishers cannot put out the enclosed fire.  The fire then spreads quickly to the rest of the vessel through all the flammables that are readily available, such as the wood trim and foam cushions. Soon the very fiberglass the boat is built from is burning. Ultimately, leaving no alternative but to abandon the vessel. The vessel burns to the waterline.

The key to fighting a boat fire is done at the dock before you leave the marina.

Here are the USCG minimum requirements for fire extinguishers onboard pleasure craft

  • For boats under 26′ – At least one B-I type approved hand portable fire extinguisher.
  • For boats 26′ to 40′ – At least two B-I OR one B-II type approved hand portable fire extinguisher.
  • For boats 40′ to no more than 65′ – At least three B-I OR one B-I plus one B-II type approved hand portable fire extinguisher.

Keep in mind that these minimum requirements are exactly that; the absolute minimum. A B-I type extinguisher equals 2 pounds dry chemical. A B-II type extinguisher equals 10 pounds dry chemical. These portable fire extinguishers are also rated to the class of fire they will be able to put out.

  • Class A: Ordinary Combustibles Includes wood, paper, cushions, canvas, fiberglass, rubber, many plastics, and other materials that burn easily and account for many boat fires. These can be extinguished with water.
  • Class B: Flammable Liquids Includes gasoline, propane, diesel fuel, oils, grease, paints, tars, lacquers, and flammable gases.
  • Class C: Energized Electrical Equipment Includes wiring, fuel hoses, circuit breakers, machinery, and appliances.

You will likely be using an approved BC Class (although it may be ACB) extinguisher. Using a portable dry chemical extinguisher will allow you to fight a fire ONLY if it is in the first couple minutes of a burn and you can spray the extinguisher at the base of the fire; after that, you are using the extinguisher to fight the fire as you exit the vessel. A portable fire extinguisher should be kept handy between the galley and the exit and a second one near the engine room.

Now for the engine room. Because of it’s caustic, noxious agent, discharging a dry chemical extinguisher into a fire may cause damage or even destroy the items that you are trying to protect. There is a superior, modern extinguisher medium (agent) called FM-200. This unique product leaves no residue and is safe to discharged near any electrical or mechanical equipment. FM-200 is even safe enough for discharge in occupied spaces! FM-200 systems reach extinguishing levels in 10 seconds or less, stopping ordinary combustible, electrical, and flammable liquid fires before they cause significant damage.

For use in enclosed spaces like an engine room, there are two operation modes available for Sea-Fire FM200 systems; automatic and manual / automatic models. A Sea-Fire automatic extinguisher is activated by the attached temperature sensor valve. Discharge will occur when the sensor valve temperature rises to the system activation point as shown in the specification table and on the label attached to each unit. The manual / automatic offer the ability to lead a manual discharge cable to a position outside the enclosed compartment (often the helm station) so that the extinguisher may be operated remotely. If an automatic / manual extinguisher is not activated manually, it will work as a normal automatic model and discharge when the system activation point is reached.

Sea-Fire manufactures FM-200 FD Series manual and automatic fire extinguishers for areas as small as 175 cubic feet and up to 1500 cubic feet.  The Sea-Fire FG Series are made to fit small engine rooms an other closed areas, from 25 to 240 cubic feet. Sea-Fire also manufactures the FT Series which are supplied with long, flexible narrow tubing that can reach into hard to access areas; such as the backside of electrical panels for spaces from 25-150 cubic feet.

In summary, dry chemical fire extinguishers are fine for trying to put out a fire on the stove, heater or open area. Sea-Fire FM-200 extinguishers are useful in enclosed spaces, occupied spaces and hard to reach spaces.

Remove Salt from Your Boat, Engine and Marine Equipment

Looking for a way to remove salt from your boat and other marine equipment including boat cooling system, cleats, other metal and fiberglass parts?

Salt-Away salt removal washing concentrate uses a carefully selected blend of ingredients that will provide optimum cleaning for your boat and boat engine. Salt-Away washing concentrate provides salt removal from virtually any surface.

Salt-Away uses a water-based 100% – Non-Hazardous, Non-Toxic, and Biodegradable blend of ingredients that dissolves salt crystals from surfaces. Water alone cannot do this.

Salt-Away flushes salt from inboard/outboard engines.

Many boats have engines using a fresh water closed cooling system. Some boat owners do not realize that the raw water side of the engine, where salt water passes through the heat exchanger and out the exhaust manifold, can have major salt corrosion problems. Without proper maintenance, this corrosion leads to expensive repairs.

Salt-Away has many uses:

  • Engine flush – Can correct engine over-heating by breaking down layers of salt accumulation
  • Cleaning diving & fishing gear
  • Seaside home maintenance – A/C units, patio furniture etc.
  • Power & Sail boat salt removal – sails, sail covers, line, hardware etc.
  • Boat trailer and trailer brake wash

Salt-Away is economical to use with a dilution rate of 500 to 1 ratio.

The Salt-Away SA32M Combo Kit combines a one quart Salt-Away concentrate bottle and a 6 oz capacity, re-usable Mixing Unit. The Salt-Away Kit is recommended as the “Starter Kit” for the Salt-Away salt removal product line.

  • 6 oz Salt-Away concentrate holding capacity
  • Mixing Unit connects to
    • Garden hoses
    • Pressure Washer in lines

Salt-Away cleaning solution can be used with other Marine Engine Flushing systems and units to keep your inboard and outboard engine cooling system clean. When used with other Marine Cleaning Tools, Salt-Away removes salt build up and gets parts and surfaces ready to protect with wax or polish.

Stiff or Sloppy Mechanical Boat Steering

Is your boat’s mechanical steering system stiff or sloppy?

As steering cables age, they develop excessive play, stiffness and in some cases they freeze up.

So what does a boater do when their boat’s mechanical steering system needs relief from these signs of age?

Uflex USA offers solutions with both Rotary and Rack & Pinion Steering Kits and replacement cables.

Go2marine recommends the Rotech Rotary System for outboards under 150 HP as well as Inboards and Sterndrives for it’s versatility compact design and positive feel.

What makes the Uflex Rotary Systems different from the competition?

Uflex USA offers a patented helm unit with a planetary gear system consisting of 6 points of contact that results in a smoother more positive feel at the helm.

Weather replacing a Rack & Pinion or a Rotary System the Uflex Rotary System will bolt up in place of your old system without any modification.

What about larger outboard engines and sterndrives?

For larger outboard engines and sterndrive units (without power assist steering), Go2marine recommends the Accura System with the Zero Torque Feedback Helm Units. The Accura System utilizes a spring clutch helm unit that eliminates the continuous load on the steering wheel so you don’t feel feedback torque.

Uflex USA also offers the components you need if you are looking to add, upgrade or convert your Rack & Pinion or Rotary Steering System to a tilt helm.

If you need help identifying your old steering system, finding replacement cables, helm units or measuring for a new Steering System call the specialist at Go2marine (800) 998-9508 or shop online at Go2marine.com.
