Anit never dunked mine yet!!
I did not follow the 1" up per 12" rule, first I did not know about it, 2nd I think it would have been to far out of the water?
The only time it comes close is hitting the breaks fast, or when I am fishing big rips.
But a jack plate on a 25 might be the ticket?? Adjustable even better just in case its to high.
You can see here how high the motor is
