We offer replacement or upgraded marine heat exchangers for boats with sterndrives including; Mercruisier, Volvo Penta and OMC. New replacement heat exchangers are offered for your inboard powered boat with an aging or worn marine heat exchanger, including; Atomic 4, Pleasurecraft, Crusader, Mercruisier, Chrysler, OMC and Chris-Craft. Go2marine also offers a complete line of diesel heat exchangers from the diminutive Westerbeke diesel to the substantial Caterpillar and Detroit Diesels.

 

Seakamp builds heat exchanger tubes and internal plates which are constructed of either copper or longer lasting copper/nickel alloy for inboards, sterndrives and diesel inboard marine engines. Seakamp, manufacturerd in the USA, also builds replacement Sen-dure, San Juan Engineering, and many other aftermarket manufacturer's heat exchangers.

 

Seakamp brings three generations of experience to manufacturing heat exchangers for marine engines. Seakamp builds heat exchangers from either copper or 90/10 copper nickel alloy for nearly any engine application fitted to pleasure and commercial vessels. Custom orders meeting the unique needs of the vessel can be manufactured and supplied in a timely manner; we know that you can’t wait weeks for a replacement heat exchanger!

 

 

Heat Exchanger Construction

 

Heat exchangers are typically constructed of copper cooling tubes or of a copper nickel alloy called cupro-nickel. The copper nickel alloy is most commonly done in a 90/10 ratio although 70/30 is available in limited applications. Heat exchangers built from 90/10 cupro-nickel tubes offer increased resistance to salt water corrosion and biofouling. Cupronickel does not corrode in seawater, because its electrical potential is adjusted to be neutral with regard to seawater. Almost any marine heat exchanger Go2marine offers can be modified for your custom needs; including size, materials, brackets and fittings. Contact our engine parts specialists to help you with your order.
