Problem with a new 42 Cigarette
 

I'm having a problem getting my new 42 cigarette on plane anyone have any ideas?

Set up:

Twin Cobra 750hp
Bravo XR Drives
34 Lab Bravos
Top Rpm 5600
Top speed 91mph

Thanks,

Does the boat have transmissions? If it does are they in low gear when you first take off?

Buy a Donzi!!:D

No realy, I have no idea...

:p

Wow!
 

Are you guys for real I though i might actually get some good information from you people.

Yes the tabs are all the way down and the drives are tucked in. It starts to break loose at about 3000 rpm and will co right to the limiter if i let it. I was thinking about getting hering 5 blade props.

The five blades will cure the problem. When I picked up my boat it had 34's also and would not get on plane. Mercury says that is their worst prop.

It's the props. Too high pitch and high x. I would put in 1.36 gears and use 30" props. Don't know if they make 34" 5 blades?

Get the Herrings not only will you plane off better but you will aslo pick up a couple miles per hour top end and ussually a lot in the cruise range. For not try not putting your taps all the way down. I find that all the way down tends to make them more like water breaks and can hold you back. You could also maybe add some weight in the bow to keep it lower as you plane off. Those are just temporary tell you get your new props.

the boat has 28" centers the ratio is 1.5 and has extention boxes also. I had 32 normal bravos on it first and it did a bit better but I could hit the limiter to easy.

Audio may be right, Try NOT putting the tabs all the way down. My boat has a higher x dimension and will not get on plane with the tabs all the way down. Sounds strange but it is true.

I HAD A 388 SLINGSHOT
 

IT WOULD NOT GET ON PLANE WITH THE TABS DOWN, AT ALL, I THINK IT MAY BE THE STEPPED BOTTOMS, TRY IT OUT

I have tried not putting the tabs down and it does not help.

One other question for you, do you have drive showers. If the pickups for the showers are too low they will cause cavitation while planing out. Innovative marine made their pickups adjustable for that very reason.

Try a set of 30" before switching ratios. Your RPM's will be different and top speed will be lower but for testing if it will get you on plane better it will work fine. My boat is different (38' Powerquest) and tabs down is bad. It lifts the stern too much and the props cavitate. I usually leave the tabs level or slightly up. Run it up to it starts to slip and hold it there until it gets up on plane. 5 blades will help, another on this board with a PQ switched an noticed a big difference.

This may not help since my boat is 31' but if I try to plane at 3000 rpm it will break loose, props are Bravo 32's. It may take a while but slowely try to plane at 2000 rpm and push slowely up to 2500.

The boat has no drive showers on it. If any of you were at the poker run in cleveland you might have seen the boat. Its white with black tiger stripes on it.

Call Phil Lipshutz at Lip Ship Marine in North Miami. Tell him all the info and he will be able to set you in the right direction. When it comes to Cig problems he is my first call. And do yourself a favor when you call. At least buy a T-Shirt or something. He will answer everyones call and give out accurate/quality information but the man still works for a living.
Lip-Ship Performance: 305-933-9988 If you own a Cigarette in FL your going to need this number, But if you own one in CA you'll want mine. Good luck!

Bravo's don't have transmissions they shift in the drive.

I'm confused what's on 28" centers? The drives if it's a side by side setup that's impossible!!!! Some of the racers know what I went through with the centerline on the F2-69 Cigarette....We had to like, really grease and lube the motors to get a 33" centerline to fit let alone try changing plugs.

I also see your running boxes did you change the X when you put the boxes on or did Cigarette do all of the installation and rigging setup?

Audio is right though buy the Herings you will not be dissappointed and in the long run it will probably be cheaper than all of the things you're about to get into trying to get it the way you want it. Call me 949 289-0059 anytime.

IDRPSTF did the guy call you yet or not??????

sorry its 38" centers not 28" oops. Hey guys thanks for the input I ordered the Herings today.

Ditto on what Ron said about the drive showers. I know you said you did not have them but for others reading this post if the tips are too deep prop blow out can occur. Had this problem with a 25 Mirage Plus and I shimmed them up just a tad, problem solved.

Tim T.

Who did the set-up? And where's the X located?????

Call me!!!!! I have a couple of options you may want to try!!!

Sean,
Thanks for the education!!! I wasn't sure if they did on a boat that big. When I posted he hadn't stated that it "blows out props at 3000 rpm" yet. I have to agree with some posts that he needs more blades in the water because I'm sure those motors have alot of torque and need a prop that bites to really get moving.

I have a little 24 footer but have 575 HP and the only prop that I can use is a Bravo 1. All others I have tried I can blow out at just about any time.

Dave

Have you tried a Hering on it and what pitch are you running?????

Sean, what do you mean by the X . The setup was done at Cigarette.

X-Dimension...Drive height in relation to the bottom of the boat. And if Cig did the set-up that means Neill did the setup so if you roll into the power gradually does it blow out the props and if it does how long does it take them to catch up and start to bite??
Sean

Sean is right 99% on the bravo /trans, but Imco has a protype setup with a bravo drive with a transmission, they used it on the 25 ft eliminator, that Teague went 144mph in, with this setup you use both gears in the top so it is stronger, instead of one for forward and other for reverse

Sean,
I run a 26" prop and I only wish I could afford a Hering prop. Plus where I run my boat it is shallow and I wouldn't want to risk a big $$$$ prop meeting with the bottom!!!

keyslife, e-mail me @ [email protected] - Rick Conti

What pitch and diameter Herrings did you order? Are they really $2500 each?

boss has baja 36 ft twin blown 540 and # 5 drive to plane drives in, tabs down, 32-17.5 cleaver 4 blades 5000rpm about 30-60sec then you feel it hook up then raise tabs and your up
hope it helps:D

Hey Stinson.....


Lupe says Hello.....

Lupe what's up bro....He's going to try a Hering 5 blade first and then spacer if need be....How's everything in So Fla?
