Checking the Seawater Pickups

1. Ensure that the water inlet holes for the seawater pickup are clean and not obstructed.

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.

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.
