I have a 17 foot bow rider with a 90hp yamaha outboard. It had a 13.25x17 aluminum prop on it and was over revving. I just replaced it with a 13.25x19 Michigan wheel apollo stainless prop. I love the new prop. I had to grind the trim tab about to fit it but it does 42-43mph at 5800rpm now and was doing 36-37mph at 6300rpm before with two adults and two kids on board. The only problem is my fish finder used to work for depth at all speeds and now unless I am you f super slow it wont read depth and also it now causes a bit of a rooster tail from the sensor that it didn't before. I am not sure why this is happening or how to fix it but it happened as soon as I changed the prop and put it back in the water
