Would this make the boat too unstable and would the transom be rated to carry this size of outboard?
I have used a tornado 5.5 with a 75 4Stoke and it goes well enough would think a 5.3 with a 80 would be quick enough for most.
It is most unlikely to be rated to take a 140. should have a plate on it stating what the hull is rated to from the manufacturer ?
