Pitch - That is the space a propeller travels in a single full revolution. A minimal pitch provides higher acceleration and a higher pitch features a bigger prospective for increased speeds.
When the cup is on the idea Yamaha outboard motors on the blade, the blade has an elevated rake angle and a greater bow lift. In the event the cup is to the trailing edge, it correctly increases the pitch dimensions, along with the propeller will create much more electric power at the price of engine velocity.
to check the prop, run the boat at WOT and observe the most engine RPM on a tachometer. When the RPM is underneath the encouraged working array, switch to your propeller with decrease pitched blades. In case the RPM is greater, switch to some propeller with greater pitched blades.
