I'm looking through the previous owner's service receipts on my 03
Bayliner 185 (4.3L) boat. The dealer is charging $600 to change the
engine and drive oils. This seems like something I should be able to
do myself. However, I'm trying to find out the following...

1) Does my engine have an engine oil drain or do I have to pump it
out?

2) I see that changing the drive oil requires some sort of kit to pump
the new oil up the drive unit. I don't see anyone who sells this pump.
Is this something an owner can reasonably buy?

3) Does my boat have an outdrive water pump? The engine has a standard
car water pump so I was surprised to see references online to a sterm
drive water pump as well. The previous owner said something about
having to change a water pump every 2 years.

4) I believe I have an "Alpha" drive. I see there is a zerk fitting on
the outdrive. However, I don't see anything in the manual regarding
what should be put in it (standard grease?) and how often/why.etc.
Usually zerks are put on places that require regular lubing.

The dealer quotes $1000 to do an annual maintenance. I'm thinking I'm
handy enough that I should be able to do some of this myself.
