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.


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.

Air-Cooled Condensing Unit

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.

Generalized Keel Cooled Set-up

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.

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.

Go2marine has many more items to help boat owners care for, maintain and repair their boat. If you have questions about the care and upkeep of your boat, check our site or give us a call at (800) 998-9508

Improved GM Reduction Starters

Sierra has redesigned their line of permanent magnet marine GM Reductions Starters for 2020

The Sierra improvements to their GM Reductions Starters include:

  • Starters  now have all steel gear construction for a longer more reliable life on your boat.
  • Starters include a more efficient solenoid requiring less amperage. The previous solenoids could potentially over heat and fail from low marine battery voltage.
  • The upgraded starters are designed to reduce water intrusion with an improved housing that seals off the internal components.
  • Sierra has introduced a one way Duckbill Drain Valve in the event of moisture or water entering the starter housing.
  • Sierra is now painting the starter housing to reduce rust and corrosion found in the marine environment.

The updated GM Reduction Starters include three models that fill the needs of many power boat owners and include

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

Direct Replacement Mercruiser Sterndrives

SEI Aftermarket Sterndrives

SEI Marine Products manufactures direct replacement aftermarket Sterndrives for Mercruiser R, MR, Alpha One and Alpha Gen ll drives. All current SEI Replacement Drives come with a three-year, Fault-Free warranty even if the failure is due to lack of lubrication for engines not exceeding 300 hp.

*Note* your current Mercruiser Drive must have both trim and tilt to use a SEI replacement Drive Unit. If you are not sure about this look at one of the Hydraulic Cylinders on your drive. If the hydraulic cylinder has two trim hoses connected to it, you have trim and tilt. (Some early model Mercruisers only have one hose connected to the Hydraulic Cylinder and SEI Marine Products does not make a replacement Drive Unit for these applications.)

Early Mercruiser Sterndrives (pre 1983) with inline 4- & 6-cylinder engines require a shorter yoke size of 8-1/8” vs. the later style yoke measuring 9-9/16”. This is not a problem as SEI offers replacements for these models as well.

Do you need help Identifying your Drive Model?

The easiest way to determine your Drive Model is by the Drive Serial Number. However, that is not always an option.

The Mercruiser Pre Alpha, R, MR and Alpha one (with Trim and Tilt) were manufactured between 1975 -1990. The Alpha One Gen ll started production in 1991 to current date. If you are not sure because of modifications that may have been performed by a previous owner here are a couple ways to identify your drive:

  1. Gearcase shape:
    • On Pre Alpha and Alpha One Drives the top cap on the Gearcase is square in shape
    • On Gen ll the top cap is rectangular in shape
  2. Note the mounting location for the Hydraulic Trim/Tilt Cylinders
    • On the Mercruiser Alpha One & SE106 Drives they are located at the very Back of the gearcase
    • On the Mercruiser Gen ll & SE116 Drive Units the mounting location is approximately 6” from the end of upper gearcase

Twin Engine Applications for Mercruiser Alpha One / SE106 & Mercruiser Gen ll / SE116 Drive Units

If you have a twin-engine boat, there is a good chance the port drive is a counter (LH/left hand) rotation drive. SEI Marine Products makes counter rotation replacement lower units that can be ordered separately as well as completer counter rotation replacement Drives.

The best way to determine if you have a counter rotation drive is to compare the port side propeller to the starboard side propeller. Looking closely at the propellers you will notice the port propeller twist to the left and the starboard propeller twist to the right on counter rotating drives. If you do happen to have two propellers that twist to the right, you have two standard rotation drives. This is not uncommon on early twin engine applications.

Gear Ratios

Drive units come in different gear ratios to best match power output of your boat’s engine.

If you can’t read the gear ratio off the drive, there are a couple ways of determining the gear ratio. One way is by the engine model and hp. The other way is to remove the upper cap on the drive and count the teeth on the two gears. Below is a chart to help you find the gear ratio for your boat’s drive.

If you have any questions, call a specialist at Go2marine for assistance before ordering by engine or tooth count.

Electronic Ignition for Your Boat’s Engine

Pertronix offers Electronic Ignition Conversion Kits for most engines with conventional contact type ignitions used in the Marine Industry.

Pertronix Electronic Ignition

Pertronix Electronic Ignition lets you get better performance from your boat’s marine engine.

Standard contact type ignitions (points and condenser) are unreliable since as the points wear, the ignition timing is reduced causing sluggish engine performance.

Installation of Pertronix Electronic Ignition kits is as simple as removing your old points, condenser and breaker mounting plate then installing the new Flame Thrower Module in its place. You’ll adjust the ignition timing one last time and will have a modern high performance, maintenance free ignition system.

With the addition of a Flame Thrower coil matched to the Electronic Ignition, the voltage will increase from 24,000 volts to 45,000 volts resulting in quicker starting, better overall performance and increased fuel economy.

See the Pertronix Ignitions and coil to find the one right for your boat. For technical help or engine application questions, call Go2marine @ 800-998-9508
