I am considering purchasing a 20' Seacraft built in 2004. It currently has a 150 Merc 2 stroke on it. I'd like to repower it in the future with a Yamaha 115 four stroke (366 lbs). Does any body have this configuration? How can I estimate performance?

Having read many of the threads here, I recognize the issues with heavier, higher hp motors. With me weighing in at 300 lbs, it appears that I have to be cognizant of the weight of the motor to minimize wet feet at the transom.

Any insight would be appreciated.
