I wasn’t trying to be rude.. You could race it in Sport GP. You’ll probably want to bring swim trunks and spare pistons. But it will be a good time. [emoji1303]

Nice work on this. I raced with these engines for many years when they came out in 1998. Built a ton of race engines and quit counting the number of thousand dollar bills. As others have said water intake is going to be a big problem and with the mods to the exhaust you won’t get anywhere near...

I have a bunch of 951 parts I need to clear out.

Hi Teodor I’ll try to dig out the diagram this week.

old article but here it is.. https://newatlas.com/supercharger-performance-kit-pulls-300-horsepower-from-kawasaki-jet-ski/7709/

Back in 04-05 ish, Riva had a vortec supercharger kit for the 15F. It was much smaller than the newer kawasaki SCs. Might be worth a search as it would likely be easier to install due to size. I do remember those being problematic for the race skis blowing belts though. But they were fast for...

Dump that engine if you can. They were not great to begin with. There were lots of changes for the 300/310 engine to improve reliability. The 300 supercharger is much larger and heavier though so this would be a big challenge for a standup hull build. Also do not put that back together without...

Going to be very loud for sure.. might want to put a water injector in the tail pipe. That MIGHT help a bit.

Don’t use that water routing..

Also note the manifold to cylinder gaskets, need to be custom cut to allow proper flow. I may still have a few sets. The Factory dry pipe manifold does not match perfectly to the cylinder. Also I had to back the compression way down to eliminate the mid range hit with dry pipe. It was almost...

I have a water routing diagram I’ll dig out. I published this to Dasa, 10 years ago and they started adding the side ports which are needed to keep hot spots from forming. Basically its a dual line cooling setup off the pump. (1) line for exhaust cooling and (1) for engine cooling. What...

Hi guys Hard to believe this post is 10 years old. Now I feel old. Ha! Amazingly I still have this ski. (Monster Dasa 900 SXR). Its the fastest SX-R I have ridden, (mid 60s) So I kept it mint and only ride occasionally. Parts are now very rare for this engine so I don’t want to grenade it.. .

Interesting build,, you may want to check weight and balance. The SC is heavy and it may lean way too much in a ski. Even the heavy ultra hull will list to the SC side when floating. May need to add weight to balance it out. Good luck on build. [emoji1303]

I use scotch brite pads on mine. Purple course then green then WD 40

I was never able to get super rich low speed jetting to work in any Novis. 1/4 to half throttle always sucked. Try 125 pilots and 150 main

Looking for a new or mint condition cover. Looking for the kawasaki OEM cover. Gray or green Thanks Larry

The 800 pump is actually stamped 750. The water fitting is different though.

Man don’t make it a freestyle ski.. Its a race hull. So many other choices for freestyle these days. Make it a super clean limited 750. It will hold value well. These are becoming rare to find parts for.

Most of the female coupler ends have a screw tip you can loosen and tighten to adjust fit on the zerk. Try adjusting the tip. Lock-n-lubes work well too if you have space.

I like klein tools in general.. the screw drivers are great too.
