    Higher elevation issues.

    Hull appears to be fine. Local boat shop recommended a 15.6 X 13 3 blade Turning Point. So I tried it Sunday. Boat hopped up on plane and had plenty of throttle left. So now I just need to get back up to the higher lake and see what happens. I can’t thank all y’all enough for sharing your...

    No I haven’t even thought about it. Totally makes sense as something to check though! Thank you very much.

    I agree. That’s what led me to believe the motor height is wrong and I need to drop it a notch. There are so many variables though, where do you start? Weight distribution is a factor as well, right?

    No, I am leaving it down until it gets up on plane. Then if I touch the trim at all the porpoising starts.

    Higher elevation issues.

    Okay tonight I went to a Lake here in the Valley. With an elevation of 2531’. Running the 3 blade stainless 14 1/2”X17 prop. I had my son and I in the boat so roughly 450lbs. The boat took quite a while to get on plane. Once it did I got up to 36.1mph by gps at 5800rpm. If I touched the trim at...

    Jimbo, what should it be? I watched a couple setup videos and read some forum stuff and websites. Yes it is new to me. And having a prop boat is new to me. So I’m trying to learn what I can.

    Thank you Dave! Yes I have tried 2 different props now. The 1st had a slip in hub. The one I have on now is a hub that looks like it doesn’t come out very easily If at all. I can get pics if it would help. Correct, it will not get on plane at the lake with an elevation of 5,070’. I thought EFI...

    No weeds, rope, or fishing line that I could see. What do you mean by flaky?

    Thank you! Why would there be such a difference though from a lake at 4,700’ to a lake at 5,070? I did think about cavitation. Would that be from the motor sitting too low in the water? I’m pretty sure I’ll need different props after reading what I have. Oh, duh, that makes sense. Thanks!

    I’m sure part of this topic could belong in another forum. But I’m going to include it here too. Yes this is my first post. No, I’m not new to reading the forum for all y’all’s wealth of knowledge. I just bought a ‘18 Thunder Jet 18.5’ boat with a 115 four stroke CT. I bought the boat from a guy...
