I don't really care how fast mine runs I just want to get the most out of what I've got! I have a 20' LaveyCraft tunnel with 454 MAG and 26" Hydromotive and it will only run 78 on GPS so 80 in a 26' seems impossible.

Like I said though any help getting it dialed in as best as possible would be appreciated. I read all the old forums about this boat and how to drive it. Can't wait to get more seat time!

Thanks,
Andy

Hey NASHPDA.

I'm in Knoxville. I Want to visit Old Hickory this year.

Hey used parts,how fast u goin with 1200 hp??? and i got a 30 with 3 200 merc obs,goes 70,when u trim it out it SLOW'S down those guys are tellin the truth!!! it likes the pad,when u get on it its like no other hull,u can feel the lift tripps

Just sent you a PM. Give me a call.

Ok I got to drive my new 2000 260 this weekend. I really enjoyed it but had a lot of porpoising from about 55MPH on up? No problem with chine walking. It has a 24" Bravo 1 on it now. I'm going to try a 26" Hydromotive 3 blade this weekend and see if that helps. Best I saw with Bravo 1 was 68MPH at 5200RPM and lots of Porpoise.

A 260 (24+Platform) will run mid 70's GPS on a 454 mag mpi, EMI exhaust, Arizona speed and marine upgrade, and prop work. That is @ 450 HP, 5350 rpm, and 26" Hydro 4 blade.

600 hp in a 260 should put you to mid to upper 80's.

525 in a school bus windshield 290 will hit 80.

Minus the silver bullets. Oh and Hyper. I already did.

I know everyone is saying not to trim out too much. But trimming out seems to be the way to stop the porpoise. Should I see a noticable rooster tail at full out trim? I don't have any tabs and have been told that I shouldn't need them on this boat.

Thanks,
Andy

Mine likes to ride right about the trim level when you start to see that little rooster tail form. The best way is to keep an eye on your tach and speedo. As you trim up, you should gain rpm's and mph's. When you see those start to decrease, tap the trim button down a hair and you've found your proper trim setting.

Once you get the hang of it, you'll know just what to do, without looking at the gauges.

I get on a plain, tap the trim up button 3 times and that sets me good for cruising speeds. When i go balls to the wall, i put the stick to the dash first (coming from cruise speed) and start trimming up till i hit 5200 rpm.

On calm water mine will porpous a little at 55. I just leave the drive tucked in a little and run my tabs a hare below neutral. Seems like its worse with people in the back seat. I would try some different props.
