So my buddy has a 25” 225 on his fishing boat. Recently he noticed water leaking out of the mid between the can and the saddle, up by the upper motor mounts. Leaks out a pretty decent amount of water. Still pisses fine and doesn’t overheat. I’m not 3.0L savvy.....never had one apart. I see a small almost like aces hole in that area where I can see the driveshaft turning - could it be flinging water from like a leaking water tube grommet? (Thinking 2.5 world idk). Anyone?

Most likely it's the powerhead gasket.

This is kinda between where the tuner plate and the can come together....almost under the lower motor mounts. Could the powerhead gasket be leaking and it’s like running down? I took the lower pans off to see more but that didn’t really help, as it’s coming out that little access hole right under the motor mounts. Weird thing is it doesn’t do it all the time.

Oh, I mis understood. Believe it or not, that is kinda normal. I have one 20'' 3.0 that has done it for yrs. Even a new base gasket didn't fix it. Still leaks out lower mount area. All's normal otherwise.
