    There is no way of knowing for sure until you try both props. See which prop delivers better performance. You may not notice alot of difference on a pontoon boat between the two.

    One is a 10 pitch (10p) other is a 9 pitch (9p).

    Without a tach, it would be difficult to tell which one is more efficient for your boat.

    Put one of those props on a 40hp on a 16 foot jon and it would jump out on plane, but not get the best top end speed and your motor would well over rev.

    You need a tach on the boat to tell.
