I've got bilge pump problems and bilge water issues. I also think, for the most part, I have a handle on the problems.
I have a front and rear bilge pump. The first image below is the front pump (I think ... as for the perspective, I'm holding a phone deep in the ski locker and the view is looking aft). The second image is the replacement listed on nautiqueparts.com.
My problems are these. Neither pump is working. When I switch them ON, there is a humm sound from the rear, but nothing in the front (which is just underneath my feet at the helm). Perhaps the rear is jammed, but the front is dead.
1 - what's a good way to access the rear bilge pump? I'm sure it will take removing the partition wall between the engine compartment and sidewall. Do I have to take out a ballast tank?
I have searched this site and have not found pics of the location of the rear bilge pump. I'm sure I saw it when I did this.
2 - anybody use a dispersant in their bigle. My bilge water seems to have gelatinous mats of something, about the size of a quarter to half-dollar, and are fairly near neutral bouyancy, although sink when the boat is at rest long enough.
