Well, I don't know diddle-squat about hondas. Nothing....

It really isn't the motor that can run high or not, it's the prop. Prop will usually let go before the motor says quit...*usually*..

Champ hulls for the most part really like high rake 3 blade props, tempest, yamaha M's, T1's, RXS powertechs, all are the deal. Four blades are usually reserved for handling in extremely rough water.
