Have You Guys Ever Wrenched On A Boat To Kno The Effects Of Moving The Center Of Grav? Can Tou Tell Thats Where They Originally Should Be, Why Would They Build It Like That, And Now You Need Them Moved Back? not saying you dont know but it ran well before, there are things you can do to props to change the way it handles, i just cant see all that work for nothing.
Jason, tell us whats going on. If nothing else, we would like to arm chair engineer this thing with you. |

I am with you. I have been involved with the setup of more than a few boats. This seems drastic after limited testing.

Ive had no less than Brad Schoenwald in the boat who said set-up was screwed..."let Larry set it up". This aint my 1st rodeo guys. I wasn't aware of the set-up till I ran the boat but instantly knew it wasn't right. They either were planning on putting 2800-3000 HP in this boat or had a "bright idea" or didn't know what they were doing when they placed these motors. |

Whats going on is there are multiple 35 motions which have been built with good power and sixes. They all run an 18-22inch shaft. These boats run flat and are very fast. My boat was rigged by someone in Florida who had never rigged one of these boats. My shaft is over 34 inches long. (Don't pull that out of context:eek:) This pushes the weight way too far forward. Boatstarts to climb out of the water but cant hold the bow which falls then it happens all over again probably once a second with lots of magnatude at 100. Larry Goldman has rigged about 50% of the 35 Motions. He has won multiple world championships in the 35 motion. His boats are fast and run flat. When I asked about this boat he instantly said he knew the boat. He said they mounted the motors way too damn far forward. Move them back, 18-22 inch shaft, fast flat boat, done deal.

What is that going to do to your drive shaft angle? |
OkieTunnel, I can think of several ways to change the CG besides moving the motors. That is at least twenty- thirty grand if you have it done and done right....What about starting by moving the batteries to the transom and sand bagging the transom with enough wt. to get it flat. The next concern will be getting on plane w/enough X dimension to get the props out where they belong....Do you have a ballast tank?

What do the batteries weigh....80# each ? X2= 160 x 6ft= a lever arm of 960# and that's just for openers.

hope you get it worked out okie... lets see the fountain motors johnny?? heres a pic i took before we cleaned them

Okie- I look foward to seeing you get it worked out.
At least you have a good hull and know what needs to be done. I have been in a few that were lost causes. Example, the 34 DCB that porpoised so bad that it unloaded the drives. You could drive through the porpoise in the right conditions. This thing porpoised so bad trying to get over 100 that it would unload and eventually break the drives!!! Then there this is U l t r a, The only Ultra I have been in would try to make a turn when you got out of the throttle. It is a shame what all is out there that unknowing buyers will wind up with. Get that Motion worked out and take me for a ride! |

Was that the DCB that kept breaking the tunnel tab off? The 34 is a POS! The 32 is a damn nice boat. 35 Motions are one of the best handling cats made if rigged appropriately. Mine soon will be.
Haha, the 34 that kept breaking the tunnel tab was the replacement that had 6's. |
