Maintenance
The Strainer Pro is designed to prevent weeds and other debris
that enters the cooling system from penetrating the engine and
restricting water flow. Check the strainer basket regularly for debris
and clean as necessary.
1. If there is debris in the Strainer Pro and the boat is in the
water, DO NOT disassemble the Strainer Pro before you place
the sea cock in the OFF or CLOSED position. If there is no sea
cock, remove the boat from the water before disassembling the
Strainer Pro.
2. Remove the inlet cap retainer by rotating it in a
counterclockwise direction.
3. Pull the inlet cap from the sea strainer.
4. Remove the wire mesh screen from the sea strainer and
remove the debris from the screen.
5. Reinstall the wire mesh screen in the sea strainer.
6. Reinstall the inlet cap, making sure to not damage the sealing
O-ring.
7. Reinstall the inlet cap retainer and rotate it clockwise to
tighten. Hand tight is sufficient.
Flushing the Engine
An added feature of the Indmar Strainer Pro is the built-in flushing
connection.
To flush your engine with fresh water:
1. If your boat is equipped with a shutoff valve (sea cock), place it
in the OFF position.
2. Remove the flushing protection plug from the sea strainer.
3. Attach a standard water hose to the flush fitting on the sea
strainer.
4. Turn on the water supply to the hose between 1/4 and 1/2
pressure.
5. Start engine and let it run at idle with the transmission in
neutral.
6. Turn water supply to full pressure.
