Prop Recommendation Help

[swannysonny]

Hello everyone. I have a 16ft Larson Trihull with a 1980 Johnson 115hp outboard. I spun the prop my most recent trip out and I would love some recommendations on a new one. The whole setup is mostly new to me(driven 5 times ) since I have spent the last two summers overhauling it. The old prop was previously painted and I can't find it's dimension/pitch info. I was mostly okay with it but I also was not overly impressed with the prop either. I also don't know the weight of the boat but I completely replaced the deck, transom, foam etc so it doesn't have extra water weight or anything. I use the boat to water ski, tube, and cruise around in. Thanks for any recommendations!

A 3 blade 17" is used on a lot of boats that size, it will get you into the low 40s mphwise
Your engine makes it's best power at about 5200 rpm.
