So I have found out that the tube coming out in the cuddy cabin is for
draining out water in the cabin that could accrue from rain, wet towels,
people, etc. The bilge pump will suck on this tube to suck the water out
when I turn it on.

What is happening is, when enough water is below the engine and I havn't
been running the bilge pump, if I slow down super fast to make the nose of
the boat go way down, some of that water will make its way up the tube and
come out into the cuddy cabins floor.

If I run the bilge pump for a few seconds before doing the slow down no
water will come out into the cuddy area.

If I run the bilge pump when the water does come out into the cuddy area it
sucks it right out.

So if I ran my bilge pump all the time I would never see this water, but
sometimes there would be no water for the bilge pump to suck out and it
would be running dry. Will this hurt the pump?

I have a plug for the cuddy pipe that I could plug it with and take it out
if rain got in there but I havn't tested it out yet.
