I just purchased a 2003 Bayliner 185 w/a 190hp factory option engine.
I'm a pretty handy guy and generally do all the maintenance on my cars
(I got 375,000 miles on my Celica and never once had anyone but me
work on it). So I'm looking for a Haynes or Chilton type of manual
that I can get an idea of how things work. Also, I'd like to see a
maintenance schedule. The seller told me to ensure I replaced the
"impeller" every two years but he wasn't sure what it is. I'm guessing
he's referring to the engine water pump but I'm not sure. Obviously I
know that the trailer bearings probably need to be re-greased every
season or so.

Just select the engine make (I assume Mercruiser), your engine
size/model (I'm guessing 5.0 liter) and year (03). The appropriate
manuals will appear.
