Lockjaw Posted August 20, 2002 Share Posted August 20, 2002 Man that is some wild ride. Who set up your boat? My gut feeling is one of two things are a problem. One, you caught a gust of air, or your boat needs to be re-balanced so you don't have to trim it as much to get the speed out of it. With your HP you should be able to break the century mark, but you have to be really careful with a tunnel boat. They fly, literally. I want a V-king with a promax. Now that is my idea of fun.

Andrew Bayley Posted August 21, 2002 Share Posted August 21, 2002 Sounds like your X - dimension might still be a little too low. You got a jack plate on that thing? If so, crank it higher, if not... seriously look into getting one. While not too many, I have talked to a few flat bottom racers before that say to raise the "X" as high as it can possibly go for speed. This way, an over trimmed situation will simply "blow out" the prop rather than shoot for the moon. Besides, you get a realy cool rooster tail when you do this. Also, you might want to look into a prop with a little more stern lift in it. A quick easy way to do this is to have somebody chop about 1/4 - 1/2 inch off the diameter of the prop. Might be worth asking around to see what other people have tried. All this info (which might be crap) is based on larger Offshore style boats. I had a similar situation this weekend. I was going about 60 mph and must have shot at least a five foot air. Of course, this was Lake Erie where the wave heights were equal, or greater to my air height. It was fun the first time, but after the 5,398th time, it was getting a little painful (60 mile leg on a poker run across open water). ALWAYS wear you jackets and lanyards. We've had way too many casualties this year which easily could have been avoided had both (or sometimes even just one) of those item been used. -Andy Quote Link to comment Share on other sites More sharing options...
