Forgot to add that the other two 31 models were sent back to the Challenger Plant in 2007 to have the bottoms blueprinted to cure the same problem as yours plus one had a really bad roll / lean going into a left hand turn. Anyways I do not know who could look at your bottom to help with any blueprinting. I'm in Texas and I have no idea who is any good at it in this state nor in NY. If anyone could throw out some names would be a big help for both of us. Good luck.

There is a guy in Houston that I'm told of who is really good with truing hulls. I can find that name/number if you want.

As for the NY boat, I'd look into a trip to MD: http://www.lillysportboats.net/

How much tab?

How much tab?

Just below level. My Mate had no step though.

Tabs make a huge difference in handling, and I can run faster in my hustler dragging a little tab. Jerry I have a set of 5 blades I never use you are welcome to try 1 out the extra stern lift should push your bow down a little. They're 27p not sure if that's close to where you need to be?

Thx! I do have a step, normally runn with 3 down on indicator. Neutral or level. Ill give it a try.

The folks who designed this hull have stated the 31DDC does not need them. I'm not sure I agree as she gets on plane fairly well although I've only had more than 4 riders a FEW TIMES @ I can tell the difference when I have more than 600 # of passengers. She won't ride level if their leaning to either side.

Running a 26" 4 blade Bravo 1 now and it's too much prop. Only getting 5000 rpm's . I've been promised a similar prop at 24"P @ will try it ASAP. Ilmor likes to get the rpm's at least 5300. I'm sure I know your boat!! My memory sucks sometimes!!

Thanks!!!!!!!!!!!!
