Ideal set back for Pulsare

Im sure somebody out there has experimented with how far ideal set back is for a Pulsare. What seems to be the sweet spot, 12", 15", 17" ? Where does it seem to taper off? Or does it keep going but the transom will not hold? What does factory say is max set back before transom failure? Lets hear the stories.
 
I had 10" setback holding a light 2.5 liter 225 Promax and wished I had just a wee bit more with that motor. I figured that setback would have been perfect with a heavier 3.0 225 fishin' motor. For all around use anyway.
 
I am still playing with the right trim and motor height for my 2400BRX with a 300 Pro 4S. It has 10" setback with a power lift. The combination has to be at least 650 pounds with the power lift and hydraulic steering. I haven't heard of anyone having the heavier 4 stroke that I have and all have seemed to be the lighter 300 XS. It had came from the factory/dealer with the setup and I don't expect to have any issues.
 
I got 11.5" total now but was looking at a 10" or 12" static plate to go with my 5.5" hydro jack plate. Not sure if i should stop at total 15.5" or go to 17.5". Dont want to damage the transom or go too far where its not helping anymore.
 
What is you're goal for the boat? Just top speed, all around function, driving in heavy chop? I'm still learning with my Pulsare but I'm thinking that too much setback in my often rough conditions is not going to be beneficial overall, but if I wanted max speed as my objective that 16"+ with my 2.5L would probably give me some noticeable benefits.

What kind of numbers have you seen with your setup? Im building a 2400 w/ a pro300 vrod currently. 6" hyd plate
 
upper 70s is what im after. With correct set back and prop it is likely. Ive seen Randy (Wildman) have some huge set backs to adchive top speed.
 
71 MPH, 6000 rpm, 11.5" set back, 1 1/2" below, 25p 4 blade Trophy Plus, 1 person in boat, 1/2 tank fuel, 96 pulsare, 96 225 pro max
 
Get a 3 ltr 225+ and you'll get mid 70's. I had a 98 21LD w/12" 225 EFI 26P worked Trophy Plus @ sea level to 78 and change.
 
Yeah thats one of the things i need to get is a worked prop. I got a box stock 25p Trophy Plus but i want to get the set back dialed in first.

I was at 74 gps with the bow cover on and my worked 23" Tempest at 6400 rpms.
 
What are the disadvantages of more set back. Stress on the transom and what else? I've got a 10 inch hydraulic plate and I plan to add at least 5 inches maybe 7 or 10 more. I want to know why not? Looking at all the pictures, I think most of Wildman's boats start at 10 and go up from there.
 
From what I understand is low speed porpoise and the motor getting really wet coming off plane are the down side.
 
14" is a very good number to work with, anymore will be a lot of stress i ruf water. The hey to making it work is getting the motor highough to let the prop get some air. 20' Pulsare/225opti/14" setback/28" Trophy+/ and as high as I could get it without blowing out was good for 79gps on the rev limiter. At that point, the next move would have een a nose cone and 1.62 gears and raise the motor up even more. With a good running motor and the right set up, there is no reason why you can't break 80 with a 225 on a Pulsare 2100. As for the 2400, they are a different animal all together with the steeper deadrise.
 
The biggest disadvantage going WAY back is that you lose the 'all sports' ability of the boat. Still though, these boat seem to work well from 6" back to 14" back, all you can do is experiment. One of Randy's fastest Pulsare's was for sale up here a while back and I got to look it over closely. No secrets were divulged :sssh::sssh:
The previous owner stated it was really only a good top end boat, not good for all around. Maybe he'll chime in eventually.
 
I perfered just a jackplate for watersports. I put a total 15.5 inches on my starflite. Its just not the same pulling skiers and tubes.

Wildmans boats look at least 12" and then some.

Figured WM wouldn't mind since this info is on the forum........

His 96+ MPH 2100 LD has a 12" setback bracket with a built-in 5" of pre-jack and a 4" Bob's hydraulic jack plate with 6" of lift bolted to it. That's 16" of setback with up to 11'" of lift.

...awesome for top end but like JW mentioned; how does it handle all around and in moderate to heavy chop?

I am considering adding to my 7.5" of setback and possibly a bit to the 5" of lift at some point but I run in chop a heck of a lot more than clean water so hopefully Wildman and others can shed some light on the subject.

It had good midrange "punch" and of course top end, but would have a tendency to porpoise at speeds under 40mph unless it was accelerating. Not good for watersports (pulling tubes/skiers). Slow out of the hole.

I have the "Wildman" setup. 10" static with 6" pre-jack, 4" bob's hydro.

It's the best setup I've had, bar none. You can get the motor down plenty to run whatever slop you choose or jack it up and let 'er rip! The further back you put the motor, the more lift you need to get on top in clean water. Not a cheap venture, but works very well. Little mid-range porpoise, but can be cured with throttle/trim control.
