Re: Old Diesel in Universal 25xp
Water laying in the bilge can grow algae that mixes with dirt and crud in the bilge water creating a sludge.
Water can come down the mast around the sheeves. You can also get condensation on the hard that ends up in the bilge. In the winter I usually pour a little marine anti-freeze in the bilge to prevent freezing (the pink stuff).
You shouldn't have excessive oil in the bilge. If you do, on the 25XP in a Catalina 30 check the rear corners of the oil pan as it can sit in salt water if the drain between the upper and lower bilges is clogged or non-existent (on older models). A little surface rust is no big deal. If it's rusted to the point where oil is seeping through the metal you'll need to address the problem (this can be done with the engine in place).
If you're getting a diesel smell in the bilge water or a rainbow slick start checking fuel lines.
If you have a lot of gunk built up in the bilge make sure your float switch is working. It looks like a flapper and will have a wire running back to your bilge pump. Lift up on the flapper and the bilge pump should come on. If not check the three way switch on the panel is in the "Auto" position.
Finally check your opening ports to make sure they're not leaking. If they are it's pretty easy to restore and re-swell the rubber seals with dawn and Vaseline as long as the rubber isn't badly cracked.
Just remember one thing at a time !
