What MJ wrote is prolly the best critique yer gonna get but, here goes my take on the I/O.

When it came time to replace the motor ( 165 hp ) I considered going with a bracket and OB. Would have cost close to 10K. I went with a crate 165 for 2K. I flush it every time it hits the water. No problems. The mileage is good and the boat is well balanced.
took awhile to work the bug out of owning a 30+ year boat but, I have no regrets.
