Well first thing I would try to do is a decarb, Carboned up motors will give low compression, and I don't know how much you trust you guy but I have seen & heard of more then a few motors get change for something simple as a decarb!

2nd when was the last time you change the lower unit oil? And did you replace the washers on the drain screws?
I didn't one time and got water in the lower unit.

Could be simple?? But if you can stop the lower unit from leaking then nurse the motor you might make it thur.
