Livewell Thru Hull
(1/1)
umecheme:
So... quick question regarding thru hulls. I purchased a "standard" round stainless thru hull, with the expectation of installing it for a (future) livewell. My buddy told me that this will not work, and I need a clamshell type thru hull in order to suck water while underway. I can see creating an eductor effect from moving through the water. Is this the case, and if so, what should I be using for a thru hull fitting?

You need a "scoop strainer" installed over the thru-hull fitting to direct water in. You can by the thru-hull with it already attached or buy a separate one. Mine has a ring that attaches permanently to the hull and the strainer attaches to it for easy removal at the end of the season for cleaning. If you're in salt water - bronze is the way to go, not stainless.

I do not have a scoop type to direct water in. But instead a filter/strainer type. It’s a round plate with holes to keep debris from entering the thru hull. I have never had issues filling the livewell with that setup.

It's called a high speed pickup....bronze is the standard material.

This is what I used.

Been in place for 11 years and looks new. I have it coupled with the compatible seacock shown further down the page.
Good luck. :thumright:
