If no modifications and just slapped it on, then 90 or 115 based on the weight of the motor. The 90 is 320 lbs and the 115 is 390 lbs so anymore weight and you got to compensate for it.

Tommy, I run both the 90 and 115 E-TEC. On your 20' hull with a couple of fisherman and a Bimini top I think with the 20" 2 to 1 gear motors you would see -
90 E-Tec - 3800 RPMs = 21 mph, 5600 RPMs = 32 mph with 13-3/4" X 13" wheel (4.5 miles per gallon average) Very flat torque curve
115 E-Tec - 4150 RPMs = 25 mph, 5600 RPMs = 38 mph with 13-3/4" X 15" wheel (3.5 miles per gallon average) Pipie, likes 4,150 much more than 3,900
All manufacturers 90's and 115's are very reliable - E-Tec, Merc, Yamie, Zukie, Honda, etc. and are much closer to the engine weight these boats were originally designed for. Most everybody wants more "juice". Tiny, Fr Frank, Otterhound and I are in the minority here on that subject. With the 90, I ran 55 miles on Saturday with three divers, 7 steel tanks, fish cooler, food cooler and assorted dive crap to shoot the hell out of Snookerd and Conner's hogfish off of Sarasota. I put 11 gallons in the boat to top it off on Sunday afternoon.
