Water pump

I still had water in the oil so it was not backing up. Turned out to be the water pump. There are a couple of seals on the shaft that drives it that were letting water into the crankcase. I got a new water pump along with a VERY long list of other seals, gaskets and screws. The cover that the pump was on was very corroded from the saltwater leaking on it. The lower bolt was pretty much dust.

This is the lower bolt of the pump. The X is actually the hex nuts head. The survey said it had a higher than normal level of salt in the oil. So this had probably been leaking for quite a number of years.
One thing I did learn is that the lines going into the pump just pull out. There is a rubber seal there but it does not have a thread or anything to release it. It just pops out or in. Which is tricky since there are one on each side of the pump.


Gary Woods marine of Stuart was quite helpful in finding all the parts I would need and offering a few other good suggestions about how to do it. It was not too hard of a job and it seemed to have fixed the problem. We have run the motor from Stuart to Marathon and only sailed a few of those days and no sign of water in the oil.
