OK, let me give what I know.
The boat sits about 3 or 4 inches lower, enough so that water puddles on the left side of the bow cover
The battery is on the other side (port).
According to a local mechanic who says he knows these old Maxums, there is foam in channels on either side of the ski compartment, and these channels have no drains but are packed with foam, and if the boat floods, over time the foam can load up with water.
The previous owner had a cheesey boat cover that let the rain seep in. I have better covers, but rain still gets in (I am trying to figure that out, likely at the windshield). After our last torrential downpour over 2 days, the boat was as full of water as I have ever seen it; the ski compartment was flooded all the way to the front seats. I am going to put in an automatic bilge pump to mitigate that.
I guess it is possible that the wood inside is also waterlogged so I hope that garaging it over the winter is a long term solution to that problem and the other improvements will decrease the water that gets into that area.
But I am open to suggestions.
