Re: Propeller Problem! NEED HELP!

Without a current prop and its related performance to judge, we would only be guessing with a recommendation. <br /><br />This can only be determined by running the boat with a given prop, and making note of the rpm at wide open throttle ( WOT ).<br />So a tachometer will be needed. <br />Knowing the prop pitch and the rpm data, we can make an educated choice of which prop to select to improve holeshot or top end, and to provide a WOT that is within the manufacturers recommended rpm range.<br /><br />Your boat is light in weight, so I would first try a prop that is approximately 10" in diameter and 15 pitch.<br /><br />After determining the WOT with this prop, you can decide if a different pitch prop is needed, and we can help you decide which pitch you should purchase. You will then have the correct prop, and the first prop will become your spare/emergency use prop.

Re: Propeller Problem! NEED HELP!

Thanks so far!<br /><br />I have heared of a Propeller that has got an adjustable pitch! It is named Pro Pulse! www.propulse.se<br /><br />What do You think of that?<br /><br />Could that solve my Problem?<br />Maybe with this propeller i can find out which is the right pitch i need, without trying several propellers!
