2005 BF225 Water In Oil - Advice Needed!

What is your plan with the motor?
I’m gonna pull the foot and midsection first and connect a water hose to the water tube that supplies water from the foot and try to see if anything’s obvious or maybe if I can hear anything. I’m gonna leave the oil drain plug out so if it does leak anything maybe it will run out pretty quick. After that I guess I’m gonna pull the heads and have a look. Not sure after that lol
 
What are you planning on checking next? Seems like there is several places water could enter the oil but you’ve already made my first moves
 
Pulled the lower unit this evening and clamped a water hose to the water supply tube and pulled all of the spark plugs out. I let the water run for a few minutes but couldn’t tell where water was getting in the oil because of all the water coming out of the drain holes around the oil pan. Then I hooked a water hose to the reverse flush port just to see if I could see or hear anything but no difference. So I got my son to roll it over while I watched the spark plug tubes and both of the bottom cylinders had water coming out of them. The one on the right was the worst. Guessing it was ran hot by the previous owner for both head gaskets to be leaking.
