Hi all,

Thanks in advance for any helpful responses.

I'm attempting to winterize the ol' Bayliner. How many water drains are
there on the AQ125B Volvo Penta? I only see 1 small drain valve at the
bottom, toward the back of the fresh water manifold. Are there any others?
After draining the manifold, do I need to do anything else other than change
oil, drain & fill outdrive, and add fuel stabilizer?

Thanks


Drain as much of the water as you can out of the manifolds but you should
still add antifreeze. I don't know about your engine in particular but mine
only has 2 that I know of located on the bottom rear of each of the exhaust
manifolds.

Antifreeze helps prevent any remaining water in the engine from freezing and
prevents rust inside the water passages over the winter. Remember that the
optimum combination for rust is a little water and a little air, which is
the state you leave your engine in when you only drain the block. Adding
antifreeze after draining coats the inside of the water jacket of the engine
minimizing rust over the winter. It also floods into the few places that you
can't drain easily and helps prevent them from freezing.

Though I store my boat in a controlled climate storage where freezing is not
an issue, rust is a concern. I don't want to have to change out the
manifolds any sooner than necessary.

I remove the water intake hose from the outdrive side and have another hose
and small length of pipe that I plug into the intake hose. The other end of
the hose goes into a 5 gallon bucket of antifreeze that I place on my swim
platform. Then I run the engine unil I see antifreeze coming out of the
exhaust and dropping in level in the bucket until a couple of gallons are
gone. Then I spray WD40 into the carb until the engine stalls.

Might not be the best way, but it has worked foine for me for over 10 years.

My 5.7L Mercruiser has the two drains under each manifold, and also
has one on each side of the block below the manifolds.
