What are the pros and cons of a set back jet ? Is it worth the money to do it ? O0
-
Some boats work better with the pump set back and some dont.
-
what will happen to mine 19'daytona
-
and is it worth the money ?
-
I have seen alot of 19'daytonas with set back pumps. Basicly it is a set up to go fast. It puts less of the boat in the water. I had a 18' hondo t-deck with a set back jet and it was set up for drags basicly. It did not turn but it was a rocket going strait. The nice part about a set back pump is if you suck up something in the jet your inspection cover is outside the boat! I dont know how much it will cost you because my boat was already done.
-
to reset the intake and move the pump 2500$
-
Ouch! That seems like alot of money. I would just do it myself. :)
-
im pretty new to this stuff so id rather not mess with it
-
seems like a hell of a lot of $$$$$, shouldn't the diverter do the same thing (get the boat out of the water)????
-
i dont know ??? a couple of people have told me i need to chenge the intake if i want to go fast i guess this one is for skiing ?
-
can you get a picture of where yours is at in relation to the back of the boat and i will compare to mine
-
yup one minute
-
heres a couple it looks like its about 1.5" off the floor
-
i am heading home right now, so i will check mine when i get there, but am pretty sure that my intake is set back further to the rear than yours, will let you know
-
thanks
-
ok from the back of the boat to intake is 3 1/2 inches, not sure if this will help or not, but maybe give you something to go on, how far forward is your motor? (putting more weight to the front), mine is 6 1/2 inches off the back off the boat to the back of the block (where mount is mounted), like i said, don't know if this will help or not :)
-
:-\ well the back of my intake is 7" from the rear of the boat and the block is 11" so now what ?

Hey Erik I called you a few times to help you with redoing the floor and seats etc. Give me a call
-
where is tom? he might be able to tell us what the differences will be between my set up and yours and what type of gains you would see if you reset your intake or if there is a more cost effective way of achieving the same end result ???
ohhh tom, come out come out wherever you are ;D

pm me your # blue

We do setbacks all of the time. $2500 seems REAL pricey. Call me. 623-877-8553 TUF-ENUF Marine TIMM P.S. I have a 19 Daytona with the pump set waaaay back.
-
2500 bucks is nuts for a set back.
MPD charges about 1,000 i think.
i dont see why any jet boat out there wouldn't benefit from a set back intake.
things to consider about setting yours back. with most intakes, you can machine the back of them to allow for a larger set back without breaking through the wood in the transom all the way. but, that still puts the hand hole cover right under the transom in a lot of boats depending on the angle of the transom. This means you'll need to fab a transom adapter that curves around the hand hole cover if you still want to be able to remove it.
-
The hand hole cover on my Hondo is nearly against the transom and is impossible to use. Its easier for me to remove the grate for access. Only problem is its got to be on the trailer.
-
thanks cyclone
-
no problem.
-
Set it way the fuck back there Erik. After the upcoming funeral I'll ask Dave what he and the rest of his racing buddies have figured out to be the best setup for a 19' Daytona. You can't beat feedback from all the top record holders....
-
thanks dude
-
For what it's worth, on my 21 ,Tom(jbp) set it back just barely far enougph to get the cleanout out the back of the boat. I haven't tried to use my cleanout yet,(looks like it is still useable) he had to notch/grind the back of the cover to make it fit. BTW it was far less than 2500.00
-
seems like a hell of a lot of $$$$$, shouldn't the diverter do the same thing (get the boat out of the water)????
A diverter doesn't change the position in the hull of where the pump gets it's water from and where the boat rides at W.O.T. whereas a setback pump changes both.
-
Two of the biggest advantages of the setback are the potential to gain space in the interior and get the cleanout outside of the boat. Some boats wont like the motor moved back, but my 21 doesn't care at 85mph...
-
plus, the potential for less wetted surface... Just do it. $2500 is high. If you're boat doesnt behave well the the engine and pump set back so far, then put the engine back up a couple inches and lengthen your drive line a little.
-
Thanks for all the usefull info guys
-
And definitely do it yourself. I've done two, getting ready to do a third. Its easy. reseach it(hopefully hotboat comes back...) or we can get something started here.
-
thanks agian everyone but ive found someone to do it for me
-
good to hear you're gonna do it. When are you gonna be at infinite? I might make a stop up there to check out your truck and drop some stuff off to steve.

ill be there tomorrow (saturday )
