power head removal is very strait forward on Suzuki 4 strokes , ? what do you have to loose by pulling the power head and taking a look at what is the cause of the water intrusion.

you never know it may be an easy fix or it could be a part out motor , parting the 140 motor will yield you a good return if it is deemed unrepairable.as it is now you will loose on resale.

If you end up parting it out you will get best money for the lower unit, depending on condition and availability. I found myself looking for one a few years ago during the summer and they were no easy to come by, clean used were going for $1500.

The problem with the oil cooler theory is that oil pressure should be much higher than water pressure. If it leaks oil should leak out, rather than water leaking into the oil.

You got a lot of hours out of it. Count it as a win and move on. Mine blew up at 187 hours.

I did end up selling the boat in mid-August with this motor as is. I provided my contact information to the new owner. I hope to hear what was the primary cause of water in the oil. It's still unclear. I am in the market for a newer boat now.
