    Default 1970s Monark Livewell Question

    Hi all,

    Last night I bought a 70's model 15' Monark fiberglass boat, with a 1979 Mercury 3 Cyl 70hp motor. The boat has a live well and at the bottom theirs a hole in it that goes strait through the hull. Is that how this livewell works, just fills up to the water level and the rest of the boat just floats regardless? This is my first non-aluminum jon boat, and I was under the impression that all livewells had something like an aeration pump.

    It should have a overflow/drain tube for the tank instead of a plug. The tube is a drain that keeps the livewell at a certain level and you pump fresh water full time into it and constantly recycles fresh water. It is more for maintaining a constant temp at the same time it aerates the water.
    You can probably make one easy enough
