ya, i don't get it either. i can't reconcile these two facts: one, a recent mechanic attested the engine is in great shape, great compression etc., but that the prop is too big for the engine; two, according to the prop shop next door 13/8 is the rated prop size. either the prop shop is smoking crack or my rpm guage is on the fritz. Murre comes out of the water in a few weeks. will have a closer look then.

several of us on the board are running 13/8's in a 4107...i keep wondering if the props not actually 15 or some such.

13 is about max that will fit. My 4107 get's to 3000 RPM in gear no problem. It cavitates badly at this setting, but at six knots. I'm thinking something like 13X13.

The original post though deals with a smaller engine. The 13X8 might be okay for him. I accelerate quickly to 5 knots!
