Is a 115 four stroke enough?

I have a 115 Merc (Yamaha) 4s on my 16' Whaler. I love that motor. She weights around 2500 pounds with the motor, fuel and 2 skinny guys. With that load and motor, she struggles a little to get on plane, but has amazing mid-range acceleration and a top end over 40.

A SeaCraft 20, would weigh more than that and I would fear that she might be tough to get up unless the prop were tweeked. But I think it could be done successfully.

Having said all that, I would personally consider a Honda 130 or Suzi 140 as a minimum 4 stroke. Trayder had the 140 on his 20, so he could speak to this with experience.
