update
Ok I switched the trim limit blocks to the front of the trim cylinder bolt as it should be on a Bravo 1 and took the boat out for a ride,much better,
all I have to do is accelarate to 3200 rpm and planes out pretty good,

Thanks for all the help!:ernaehrung004:

Boatnt,
Probably won't tell ya anything you don't know but....

Last year I bought a '02 340 PQ with 496HO's and 28 B-1's twin step. I was having quite a learning curve coming from a single 330 Bravo with a 23P.

Two things that helped me:
Drives down deep and full tabs. As she starts to nose back down and come on plane, I trim the drives and lift the tabs.Feels like something kicking it in the azz.
Secondly, I just raise the rpm's to about 1200-1500 for 10-20 seconds to get the speed up a bit while the hull is still in the water, Before I really try to get it on plane. But Yeah, If trying to get it on plane over 3500 RPM she'll blow out.

Just by getting the hull speed up a bit before take off makes the tabs full down less required

BTW Beautiful boat and congratulations!! If ya make it to Northern Lake Mich give us Charlevoix / Boyne guys a buzz.

great,Thanks for the info

good deal i,m glad I said some thing I almost did not write it.but I had a feeling I should.

Hey,Thanks again you saved me alot of time and agravation.

Mine is easy getting on plane, roll up to 1500 then 2800 to 3000 it pops up.I dont even need the tabs but they do make it faster.30 p bravo 4bld,1.30 gear.It will blow out if try,but thats pushing it hard.

strip how much power do you have. I just bought a new to me 388 and when i test drove it with joe and john it did cavitate as the boat came on to plane joe showed me how to just back out then get back into it was told that the motors are around 700 each and turning 34 pitch 4's as i'm coming out of a 25 baja that never had this happing Just wondering if this is natural or maybe i need to do some propping

Extend your cavation plates 4 or 5 inches, I hade the same problem. I have a 35 Nordic that was fine with stock 500efi’s I put prochargers on and had the same problem. I had a set made and welded on.

Hp is 868 at 6000,3500 and up TQ was 850+. It will almost get into boost getting on plane,Hey congrats on the Hustler, you'll have fun with it this summer:drink:30's turn 6000.I have run a set of 32's lost around 400rpm but still ran 102.

Whats your max rpm with the 34's?
I assume you have a 1.50 stock gear ratio and bravo one props?

When mine was stock it got up pretty easy,the bigger props and gear ratio loads it harder,but it still feels like its not straining much. If I'm ruining along at 3000ish and nail it, it will blow the props out. Iv driven my Buddy's and ridden in his 36 outlaw, it likes about 3600 to get on plane,when he drives it he"s over 4000.Another Buddy's 38 ts cig was the same,but it has labed props,I can be behind them it sounds like there throttling hard to get on plane.I like taking it easy getting on plane,its not like your racing,its allot less stress on the gears.This is just one/my opinion:ernaehrung004:
