I would say try tweaking the prop but it looks like your pretty close to the limiter already

Re blockoffs or Riva ones will
Stop the bouncing. Make sure your trim is way up.

You could also grab a diff rideplate. Saw one in the classifieds. Jims rideplate. Its proven to give you more speed.

no trim this is a gtx limited

thats what i thought too it is like hitting a brick wall it gets there fast really fast but goes no farther

add a pump wedge.

add a pump wedge.

says he has one already. Id look in to getting a new ride plate and some block offs, might help keep the ski in the water and on plane. Proposing/bouncing scrubs speed.

[1tommygunner1927]

Yep...he sure does. My bad, I missed it.

Remove the stock intercooler, add external intercooler, send impeller to Erik @ speedfreeks. If you can't do the intercooler, do the impeller.

Ride plate? You really need some blockoffs
