    Hello all,

    I have a 13' Gheenoe with a 2006 4 Stroke 9.9 Mercury. I have the stock prop, but I was expecting the boat to run faster than 15MPH. Would a new Prop help this? Is it worth the investment?

    This is the one I was looking at would it help at all?

    Thanks in advanced.

    I'm running a merc 4 stroke 9.9, the stock 9x9 prop
    produced a top speed of 21.5 mph. Something's not right.
    I just tested a 9x10 cupped aluminum from Turning Point,
    that gave me an additional 1/2 mph top speed
    and allowed me to mount the engine an inch and a half higher.

    My stoke Prop is not a 9x9, it says 6.5P on it? Which one should I buy, I think that may be the problem.

    Try a 9x9 aluminum for your setup.

    Forum member Noettica just tested one on his 13
    and was satisfied with the results.

    No problem Lou, if you're in Palm Coast
    I can let you test a 9x9 stock if you like.
    Meet you at Herschel Park one afternoon/evening this week.
    I'm down there testing regularly.

    There are some variations in Mercury's here are a couple of Links to follow

    13 Footers seem to have a speed Block

    When you get porpoising you need to work on weight distribution or add a stingray Jr.

    The Turning point is not bad but I lost some Speed over the Stock 10 Pitch ...

    You need to Know the number of splines

    If you have an 8 Spline I have a TON of props ...

    If you have an 8 spline I can loan you a used 10 Pitch for Shipping ... Let me know ...
