Cleaning the Seawater Strainer
NOTE: The seawater strainer can be visually inspected through its clear cover without requiring any seawater system
disassembly.
NOTICE
An open seawater strainer or seacock during some service or maintenance procedures can introduce water into the boat,
causing damage or sinking the boat. Always close the water supply from the seawater pump, water inlet, or seacock when
performing service or maintenance on the cooling system.
NOTICE
Disconnecting the seawater inlet hose will cause water to enter the bilge resulting in engine damage. Close the seacock
before disconnecting the seawater inlet hose. Plug the seawater inlet hose immediately after disconnecting it.
1. If the boat is in the water, ensure that the engine is off, close the seacock, if equipped, or remove and plug the seawater
inlet hose.
