quick question about props

[LOLHJ]

My 14' Starcraft boat has a 1986 30 hp mariner on it and it had a 9 7/8x10 1/2 F prop on it.<br />Now I just bought a 10 7/8 x 11 prop- what will the changes be? They told me it was going to be very un-noticable, is this true? <br /><br />So basically:<br />9 7/8 x 10 1/2 <br />vs.<br />10 7/8 x 11<br /><br />whats the difference?<br /><br />Thanks.<br />-John

Re: quick question about props

I think you will notice a change. But it's not necessarily a bad change. You may notice a slower hole shot,but higher top end speed.<br />Just be sure you can achieve FULL RPMs with the new prop. If not, don't use it,as it is putting too much strain on the engine.<br />It like running a larger diameter tire on your auto.

So im assuming it will be harder to pull a tuber or knee border then. I have no way to tell my RPM's- should I get a gauge? If so how do I hook it up? Whats the RPMS i should run at? Thanks for the help.<br />-John
