Does anyone use a "stuffer" or "full lobe" crankshaft ?Over the years i have been into Scooter tuning and Go Karts and this is one of the first things you normally change to alter crankcase volume .

Stuffer cranks help torque but generally do little in boosting peak RPM limits ..... boats generally go faster with rpm gains and not pulling bigger props that upset handling and control
