Re: Sea Water Strainer

Losing prime after cleaning can't happen if below wl. Checking thruhull ingress is possible too. Not so if above. At least the sea valve gets tested, which is good. The raw water pump is often below wl so a failure there is either direct from ocean or syphon over thru the strainer No matter .thats what the valve is for.

Right, as long as the Motor is running. Below the water line it will do both but at different times. That suction leak will turn into a real leak if the leak is below water line. From a point of view that the strainer is the most likely source of failure you may choose it put it above the WL but then again it might just not be practical. Choices..

Or cares? ;-)

Timely for me, regardless - I'm about to replace everything from the thruhull inward, engine included!

Re: Sea Water Strainer

Jim, probably everyone noticed. Boaty problems and opinion of solutions remain constant .It's the viewing public that changes.
