I’m looking at buying a 1988 16 footer that needs repowering. I have a line on a used 2011 Mercury 60hp 4-stroke outboard and was wondering if this is too much motor. Is anyone else running 60hp on this boat? Assuming the weight of the motor is manageable, what would be the downside? The rating plate on the boat says 55hp max, but is 5hp more enough to quibble over? Thx in advance.
