I have a 80s javelin hull I've just been playing around with and I had a 23cc bh hanson hanson in it I tried several props with that engine found that a x470 2 blade seemed to work the best and any prop with lift the boat didn't like. So this weekend I put a 26cc m&d mod motor in it and with that same prop as soon as you go near the throttle it lifts the boat up some and does barrel rolls. I know it sounds crazy but it's spinning the boat instead of the prop. I didn't have much time today to test. anyone have any ideas? I know it's a super weird old setup and just a play boat but I was wondering where to start I was kinda guessing rase the strut but it's all the way up to go higher I'd have to dremel the strut.
