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 /><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

Sounds OK to me.<br /><br />You might see a little more top end speed at wide open throttle, if you are not overloaded for your motor power/boat combo.<br /><br />The old prop (9 7/8) should give you a faster hole shot (get to plane faster).<br /><br />But it may not even be noticable.

I would check the service manual first. You are going to a larger diameter prop with more pitch. That is a good way to ruin a motor. I would stick with factory specifications for motors. My service manual gives me 5 choices, and basically the larger the diameter the lesser the pitch. <br /><br />FYI<br /><br />Arlan
