Engine thru hull

John Mackie, John William 37VT68


I removed the engine thru hull because of a leak and discovered the original thru valve is not a full flow valve. It actually is only 3/4 inch which is smaller than the pump intake. You can see a shell protruding which cuts the flow even more. I am in the process of installing an 1 1/2 inch valve and continue to use the 1 1/4 inch strainer.
