    Help, my boat won't stop bouncing

    Hey,

    I got the Mickie Beez jet drive with his jet sprint hull as well. I am running a leopard 4074 2000kv motor and a 180 amp esc. The problem I have is that even at 1/4 throttle it just won't stop bouncing. I moved the batteries almost as far forward as I could and put some trim tabs on it but am still having the issue. Here is a video of it without the trim tabs

    With the trim tabs I maybe got to 1/3 throttle. Any suggestions or insights would be great

      Is there anyway you could give the thrust some negative angle? Pretty sure its adjustable on this unit, try that and come back

          Diffidently too loose, The boat designer should pop up hear and help. I am sure he has the most experience with that hull.

              I tried giving it quite a bit of down angle. With the batteries in the front and the down angle when it goes over a wave with the up front weight it just submarined. Do you think at intake cowel would help to pull in more water and keep it planted?

                  Try putting a straight edge underneath it and look for gaps or imperfections then go get a small tub of bondo and a flatboard and start sanding, Had this problem with MG29 and now its as smooth as can be.

                      Hi,

                      which version of hull to you have? please take a photo of the bottom of the hull.
                      One thing I have been experimenting with these hulls that has made the biggest change was to lengthen the flat section forward to atleast 2/3 the length of the hull.
                      Theory is that the angle of attack of the lead in for the inlet is fighting the flow of water out the nozzle. Lengthening the flat section forward , reduces that , and as such thru thorough testing , has tamed it down.
                      To do this you lay some more fiberglass in the v section to give this area thickness, then sand off the v with a belt sander. I will post some pictures of what I mean tomorrow .
                      Another thing , these units like down trim to keep the nose more planted.
                      Regards Mick
