Okay. I'm exposing my ignorance. I cannot for the life of me understand the purpose of the thru hull fitting I have found a leak in . This is a 18 foot ski/deck boat and the thru hull fitting is located just to the left of the hull drain in the transom. On the inside of the engine compartment it has a hose which leads up under the fuel tank. This boat is not for fishing so has no live wells. What on the earth is this thru hull and hose for?
