Re: Prop
Its really hard to fine tune prop selection on small motors, because most do not have a tach.<br /><br />If you increase the pitch you could pick up a few mph, but your holeshot will suffer, making it difficult to get on plane. If you increase the pitch too much, it will drop your engine rpm down below the recommended, which will lug the engine, and can lead to fouling plugs also.<br /><br />If you decrease the pitch, you may or may not lose a couple mph, your holeshot would improve, but you run the risk of increasing your rpm to the point that you could over rev your engine.<br /><br />If you are having trouble getting up on plane, you definitely do not want to increase your pitch.<br /><br />If your holeshot is good, you could buy a prop with an increased pitch of one or two inches and give it a try. If it doesn't perform any better, atleast you will have a spare prop. Don't expect any great increase in speed.
