I am planning to install a wash down pump, and I'm wondering where I should drill the hole for the water pick-up. In my previous boat (26 Hewescraft) the thru-hull was plastic, and went through the bottom of the hull. I bought the boat used, and this is how it came.
Over the years we owned the boat, a couple of people commented that the thru-hull should have been bronze instead of plastic. Others commented that the hole should have been drilled through the transom, near the drain plug, rather than on the bottom of the hull.
Like the previous boat, the current boat is welded aluminum, has twin outboards, and will be trailered. There is plenty of room to put a thru-hull on the bottom, without a worry of hitting it on a trailer bunk, and I like the idea of being able to run the pump while moving. Any reason I shouldn't put the thru-hull on the bottom?
Any input on bronze vs. plastic fittings?
