Not a master angler, but i run a fresh yamaha 115 2 stroke on a 20' SF. No tabs, no foil, and plain and simple the boat will surprise you. The only thing it does not offer is top speed. I cruise at 25 - 27 mph 4000 - 4200 RPM all day long. WOT about 34 mph.
I was NOT a believer that the hull would perform well with the 115. My back was against the wall on an engine that i could not turn down, just too good of a deal. I have almost zero bow rise, the boat will pop right on plane and i can stay on plane as is to about 3400 RPM at 16 - 18 mph.
I am not at all sorry i went with the 115.
