I'm running a 140 Suzuki 4 stroke on my 20'. Motors about 410 Lbs.....mounted it directly to the rebuilt 25" transom. Very happy with the results....42 mph top end...5gph fuel burn at 25 mph...boat will hold plane at 15-16 mph.......the 140 Suzuki is a great choice for these hulls and won't break the bank.
