i had my set up toed in that is the prop shafts 1/4 in from the nose cones because props are turning in pushing the drives out i thought that at the end with the props pushing against each other they would torque the drives out and even out .

Thanks to everyone for the input. Boat ran great today. I hope to make some adjustments and get a few more MPH out of her next week :D

So if you were toed the wrong way what kind of characteristics would occur in your boat? Handling or speed differences?

I didn't notice any handling issues but I GAINED 13 MPH for very little money!!!! Yeah.... sounds great but it was a dog with fleas to begin with. Went from 65 to 78. Basically I fixed a bunch of issues that were killing my performance. Timing was off, plugs were fouled and the engines struggled to hit 4800. First we did a basic tune up and fixed the toe in. We gained 11 MPH and 600 RPM from that alone. We then turned the props in and picked up another 2 MPH at the same RPM. The boat pulled hard to the limiters @ 5400. I'm thinking a bit more prop would help. I think the boat has a lot of potential. It's far from the fastest Fountain around. But it's sure a lot of fun!

Question for Reggie
 

I recently purchased a 2012 Donzi 38ZR with 700's. I was told by Donzi at delivery that the drives should be towed in about 1/8" at the prop shafts to give the bow lift. The boat tops out at 109mph which is fast for a stock 38ZR with700's. Any negative side to leaving them towed in?

Could you tell us more about the reason, Reggie?
I always heard the same of what Boomer35 said.
The reason why it depends on prop rotation being that you always want props to straighten the drives, rather than emphasize the static toe-in or toe-out.
Maybe all the boats you mention were spinning props in...? After all, that's the most common setup with real fast boats! :drink:

Another free tip that I learned a couple weeks back...make sure your drives and drive indicators are even and also note where neutral trim is.
