Dear Friends,

Thanks for visiting our website. We have been here on-line since 1996, offering technical expertise and personal customer service for everything we sell. We also ship internationally to support the world-wide boating community.

Refrigeration has become a central part of the modern boating experience. We offer a full spectrum of marine refrigeration from Frigoboat, Indel Marine, and Vitrifrigo. Our systems feature the rugged and reliable Danfoss compressor. If you are looking to convert an icebox on a sailboat, or upgrade to the new Stainless Steel Drawer refrigerators, or something in between, we can help!

We launched this website in 1996 to sell Isotherm Marine Refrigeration and ever since, we have expanded our offerings so now we sell the full line of Isotherm fridges, including the energy-efficient Self-Pumping (SP) water-cooled system, and the full line of Isotherm Cruise refrigerators.

Frigoboat Keel-cooled systems - No pump, No Fan, No Noise!  An external through-hull fitting acts as the condenser, so the heat from the icebox is transferred to the water around the boat – perfect for cruising boats!

High-output alternators - we sell Amptech and Electrodyne alternators, both made in the USA. Amptech makes a 140 Amp alternator with a saddle mount that fits most Yanmar engines! It is one of our best selling alternators!

We sell Marine Hot Water heaters from Isotemp and Quick, and parts for Sigmar water heaters. We can also supply parts for the Volvo-Penta Quality Line Water heaters.

Great Water Marine Systems, Inc is the US representative for Dessalator Water Makers. Please contact us with your questions for new systems parts or trouble shooting!

Cat Pumps are used on many high quality  water makers. We are a distributor of Cat Pumps and parts and specialize in pumps for for reverse-osmosis water making!  We look forward to hearing from you.

Happy Boating !

The Great Water Crew
