props
 

I have a new to me 26' nova spyder, got all the gremlins worked out but one. It has a single 365hp that is running very good it jumps on plain quickly butttt 3200rpm/35mp 4500rpm/40mph heavy boat 5000# bottom is painted stainless prop with die grinder marks all over it and no ID marks enywher. I have no baseline to go off from no other props to compair. Looking for ideas to put together a plan.
