The Seakeeper 4/4.5 is shipped with the cooling circuit filled and ready for use. The Seakeeper 4/4.5 requires connection to a raw water pump, referred to as the seawater pump, to cool the closed loop cooling circuit on the unit.  The required seawater flow through the Seakeeper 2 heat exchanger is between 2.5 – 4 GPM (9.5 – 15.1 LPM) when the on-demand cooling system requires cooling. Prior to operation, confirmation of glycol level is recommended.

Seakeeper offers a compatible self-priming DC Seawater Pump (P/N 30331) prewired for the Seakeeper 2 Installation and covered under the standard Seakeeper warranty. The pump conforms to the seawater plumbing best practices noted in TB-90947. See Drawing No. 30331, SeaFlo® Seawater Pump Assembly, and the Seakeeper Options and Accessories Price List for details.
