The Seakeeper 3 is shipped with the cooling circuit (shown in Figure 22) filled and ready for use. The Seakeeper 3 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 3 heat exchanger is between 2 – 6 GPM (7.6 – 22.7 LPM), under all vessel operating conditions. Prior to operation, confirmation of glycol level is required.

Seakeeper offers a compatible self-priming DC Seawater Pump (P/N 30331) that is prewired for the
Seakeeper 3 Installation and covered under the standard Seakeeper warranty. See Drawing No. 30331,
Seakeeper DC Seawater Pump Assembly for details and the Seakeeper Options and Accessories Price List for pricing information.
