I’m restoring an old (1997) Cajun Bass Boat and I’m trying figure out the Live Well Design so here goes. The live well is abaft of the aft pedestal seat, it’s very large and it has three hoses hooked up to it, they are as follows.
Hose one - runs from the top of the live well down to an electric pump that runs to a -below the water line- thru hull fitting. This is the fill /aerator hose.
Hose two – runs from the bottom of the live well to a cable actuated ball valve that runs to a –below the water line- thru hull fitting. This is the drain.
Hose three – is twice as large as the other hoses and runs from the top of the live well to a –below the water line- thru hull fitting without any obstructions. This is the overflow hose.
Now I have three questions. First, am I correct with the above assumptions? Second; if so, how does hose number three release the overflow water below the water line if it does not have a pump and three, what keeps the lake water from coming into the live well through hose number three? I’m assuming it’s because the live well opening is above the water line; therefore, the below the water line lake water cannot travel up the hose? Thanks for your time.
