Is there any damage probable from rainwater submersion of the INSIDE of a
I/O (bravo) drive?

Problem 350 mercruiser with a bravo drive, 2001 year boat and under 300
hours. Boat neglected on lift, for various reasons heavy rain has filled
the boat to the exhaust risers. Needed work anyway so water in the engine
just means a new longblock, alternator, starter, wiring batteries etc.. But
the back of the outboard leg was partially submerged so - as asked - is
there any damage possible or probable to the back of the leg? Any
mantenance suggested while the motor is out.

thanks

There are three areas susceptible to water damage:
1) the unversals and input shaft bearing
2) The upper crown gears
3) the lower clutch and crown gears

2) & 3) can be verified by dumping the gear oil and
checking for water contamination.
Any water is too much water.

1) The universals and bearing are best checked
by pulling the leg off and inspecting.
They may well have corroded.

Hope this helps
