My 1981 Sport 13 has a newish 30 HP Merc EFI four stroke with T/T. With two aboard @300 pounds and six gallons of fuel and CG gear the boat pops onto plane and cruises at about 20 MPH.

I would expect very sluggish performance with half the HP but the reduction in weight on the transom could prove me wrong.
