Re: Best prop for a 24' Toon and Evinrude 115
The starting point when looking for a prop is to determine what you have now. The diameter and pitch are normally stamped on the prop barrel or on the end of the hub behind the prop nut. The next step is to tell us what the wide open throttle rpm was with an average load before you damaged that prop. That tells us whether or not the existing prop was right or in the ballpark. Without that data you are starting from scratch and unless someone is running the same exact configuration of boat, engine, load, and altitude, there is no way we can tell you what you need without guessing. The best prop for your boat is one that allows the engine to operate at or near the manufacturers recommended wide open throttle RPM with an average load. And just so you know -- even though you may not run wide open all the time, that doesn't change the fact that if the prop is wrong at WOT it is also wrong regardless what RPM you run. Since we don't have that data, I will make a swag and say a 13-3/4 x 17 prop will get you in the ballpark. Depending on the weight of the boat and altitude (which greatly affects power) you may need to drop to a 15P.
