Title: Intake location ???????
Post by: beerjet on August 26, 2009, 08:34:14 PM
So the hull is gettin a swap from the Cuzzi to a Berk.
With a littlle massaging  :P the berk intake fits in the hole  :thumbup:
Bad news is the hand hole cover is in an undesirable location for me.
What will the effects be moving it forward vs. moving it back ?

Nope ......
The suction housing was powder coated and I'm not going through that again over a hand hole cover.
I can weld aluminum so I can modify some shiz .
I'm more concerned with the handling aspect ......

well since this is team cold beer racings confidential rave hull...i am unable to answer any questions at the time...if i knew the hull i still couldnt...i guess the only advice i could give is see where other peoples pumps are set up with this hull and the hp they are making...once again i could be wrong...i just been known to have an answer for everything!

love you more!

My pump is about an inch and a half in from there, don't know how much difference it would make between the two. Best way is to try it out  ;D

If you move it forward you will need to move the motor forward, unless you use one of those drivelines that doest need a PTO.  As far as bad handling from the pump itself being forward, you could always use a bowl extension or a longer droop/snoot to make up for it, couldn't you ??

 Ironman and I have been talking about this same issue with his new project (same bottom same pump swap) and a few people have said, do not set a pump back on these boats, not sure why.  :-\

 Keep me informed of what you find out, please.

That is about where my pumps sits and there is a guy here locally that makes fiberglass inverted transom covers. Keeps the handhole outside the boat as the glass goes "inside the boat. He sells them for 225 uncut and with whitegel. I can send you a picture of what they look like if you want me too?

Ive worked on a few boats that had the same problem. I have put the pump back in with the clean cover off (so you can turn the shaft to line up the knuckle) and didnt realize the cover wouldnt go back on with the pump in so out it came. So if you dont care about being able to use the clean out i would put a little sillycone on it and tighten it down good. Dominator makes a bigger and longer transom cover that would cover all the way to the bowl if you go that route. just my .02 Matt

I set my pump back 5 1/2 inches to where the hand hole is completly out of the transom. The boat is a 18' Syndicate.I did this with intentions of running a pop off and a jet-a-way. You may run into motor clearance to the back of the boat if your not running a ratchet device or drive line. I also had clearance problems with the headers,my boat is really narrow in the back. As for the handling it definitely made it a little more squirrely. Ive seen people fill the hand hole with resin if your looking for an inexpenive way to take care of the problem.

Does that hull have a delta pad bottom?  Just curious.

Define delta pad. unsure of the term. thanks

Its got a slight curve to the bottom. I would have to say no to the delta pad but unsure. Is it still considered a delta pad if it slightly rounded?

Did you move the motor back with the pump?

Ya, with the pump moved back and a jet-a-way I ended up moving the motor back 2 1/2" for stock specs. I also had the back of the crank milled flush with the flex plate so I wouldn't have the thickness of a PTO.

Post by: zacho on September 01, 2009, 05:09:46 AM
I moved the pump and into back to nearly the same location as what your pic shows, so i didnt have to cut the transom - and not really knowing the benefits of going back any farther. Anyways, I got lucky and it turned out to be the sweet spot. See "Basketcase..." on the projects page.

I have my clean out all the way out of the boat and it is still very stable. running low 90s in a tx-19. It saved me last night also because over the holiday weekend i sucked up two rocks at he boat ramp when I was leaving. I wen't out last night and it vibrated really bad removed the clean out with boat still in the water and removed rocks. problem fixed in 5 min. don't get rid of the clean out. just my 2 cents

Omar as long as its not a delta , set it back, breach the hull at the back its plenty strong and get the cleanout so a 1/4 inch plate will clear between the cleanout boss on the intake and the back of the transom IF the inner transom design permits start with a standard length 1310 DL and go drive it, make motor movements , wedges, droops etc etc from there  , as I remember the "dead back of the transom to the front of the intake cut out will be 19.5 Just my 02 Tom

heres two done this month and last , lots more if you need pics , always here to help

Thanks for the heads up Jeff , Then leave it and "relive" and reinforce the back of the hull , machine the intake for a ride plate and shoe The Delta changes everything , just did one of those a while back too  ;)

I've come to the conclusion that the intake is going back in where it was originally.
As soon as I get over this nasty flu  :banghead: I might be able to get back to work on it.

If you were to perform a setback on a delta what would be the best way to correct the bottom?

I was considering a setback on the Hondo, am I  :screwy:
