Superramjet is running a 148mm mag in his 66E REV hull.
I'm selling my 148mm mag out of my rev.
148 skat-trak mag pump:
This setup will fit in superjets, xjets and rev hulls
12 vein non set-back
14/19 swirl
skat reduction nozzle with 6 interchangable rings
tilt nozzle and protec lever
custom titanium shaft (sj shaft won't work with the big pumps)
waterdawg pump shoe for 144 or 155 pumps
modified worx intake grate
dual cooling fittings
modified bolts (gp1200 pumps hold the pump together by attaching to the pump shoe, this is setup is like the superjet pumps).
waveblaster 2 rubber seal. (gp1200 pumps dont use this seal)
bolts in to the oem superjet pump inserts
Very nice condition ready to bolt in $1600 plus shipping
it hooked up very well with my setup, i tried many different combos. This was the best one i came up with for my big motor. I'm selling because I don't like the weight of it and how it makes my light hull handle. It wasn't that noticable in my other heavier hull but it makes my very light hull feel different.
I have a few comments/questions as I really don't think many people are at a power level to efficiently use a 148mm pump in a SJ (but I may be mistaking).
The point of running a bigger pump is to flow more volume. Is the intake tunnel of a SJ suitable for larger than 144mm pumps or would it have to be modified?
Most of the people on here today with decent sized motors are running 140mm pumps very successfully. Why would one jump from a 140 Magnum to a 148 Magnum, skipping the 144 Magnum?
Cross, by putting in a pump stuffer, you would just be negating the effects of the larger pump, wouldn't you? I would think that a 148mm with a pump stuffer would perform similar to a 140 or 144.
Observation: It would seem to me that it would be best to run the smallest diameter prop you can without cavitating/slipping. That way you have less rotating mass and can spool up faster (better bottom end).

Is the Solas 148mm different than the Skat 148mm?
I don't think you'll gain anything over a 144 Mag, except lower top speed.
I had good luck with that pump in my mild ss. It is a 6 vein skat set up. Skinnyman could give you an idea of what props to run. I had the best luck with the lowest pitch I had of the bunch. I think it was 9-17. It had great bottom end, but did lose about 1.5 mph on top compared to a 144. I gained some of that speed back by using a pump stuffer.
I wish I never sold that pump, I would love to put that in my sj project.

if prop'd correctly your ski would turn a 148 you would have very strong, "torquey" pull. My motor had so much torque a tall 144 mag pump wouldn't hook up with the tallest prop i tried. I didn't want to spend money in having them make custom props, so I upgraded the pump to run readily available props. The 148 pulled much harder, the downfall is the extra weight.
Again, please keep sending comments and feedback as this is new to me and I need all the input I can get.
Thanks ramjet
