anyone out there try the jet dynamics 155 pump shoe in there b1 ? i was going to convert a few of my skis over to the larger pump, not for speed or motor swap, but for surf and freestyle, was guessing it would pull harder on the bottom end ... ?

Re: b1 155 pump ... jet dynamics
Got a 155 pump & shoe with a 1100. Hooks up really nice. But I think you're going with a twin. Mine's a WDK.Thanks to

Re: b1 155 pump ... jet dynamics
what mid shaft are you running? i have a xl and raider short shaft but the splines are like 4 inches deaper than the stock blaster shaft, i tryed using the wr3 shaft and older xl shaft and there just a tad too long,

Re: b1 155 pump ... jet dynamics
Xl and Raiders wont work. You need a 99 yamaha gp800 with the splines toward the bearing. Ask about where the splines are when your looking for one. I bought a few and was the wrong ones.Thanks to

Re: b1 155 pump ... jet dynamics
Set back your pump. That will work.
How much too long is it with the wr3 shaft and raider midshaft?Last edited by Yamabooeey; 02-05-2013, 11:57 PM.Thanks to

Re: b1 155 pump ... jet dynamics
Lol, you're sick. Can always cut and spline. Don't know the cost though.
Put another wear ring 2" on it and move the pump back. That should still have enough splines for it to work.
The yamaha 500 driveshafts are a little shorter I think.Last edited by Yamabooeey; 02-06-2013, 12:09 AM.Thanks to

Re: b1 155 pump ... jet dynamics
i know i have a guy that will do that for free, but i am trying to come up with the parts combo that will bolt right in, will be helpful for other members trying the same build, or just good imfo for other builds, i would try the set back pump but that would only be good for handling, im trying to make a cheap freestyle boat, flat water bf at best , if its possible

Re: b1 155 pump ... jet dynamics
Oh no don't have Henry spline a shaft lol.. I would think a custom drive line company would do it for $30-50 there is one over in westside redding.( Girlfrends are cheap X2,s are expensive )
