After struggling with this same problem for years, I now reverse-assemble the 12F/15F motors. Start with the cylinders and top case half only, and drop-in each piston from the top (rod attached)...

I really wish people would stop talking OTD. Taxes vary anywhere from 0 to 10%. So at least stage what your taxes our other comparing is pointless.

Finally have the project gp out of the garage and on its home till its warm enough for a test ride. This stand works extremely well and for these smaller skis theres no reason to have a winch to get...

Don't jerry rig it and screw somebody else. Take the carbs apart, clean them, rebuild them, and be proud about selling a great running ski.

I would be looking for a stock standing jet ski. it doesn't matter if it's kawasaki or yamaha. starting from 700 cubes. I bought an fx700 (fx1) last year, this year I will try it for the first...

I'd start by checking for the most common problem... cracked head. From what I understand, if you remove the valve cover and run the motor while flushing, you'll see water bubbling up around the...

He's looking for the hi and low speed mixture screws.

Well I picked my brand new 2021 Ultra 310X up this week.

Any motor I have opened has been damn near spotless inside, even neglected ones. Unless you sink the ski, crack a head, or pop an oil cooler you aren't really going to get water in the cases. The...

You can create a service tag 🏷 that is unique to you, attach that to the engine. Maybe even put a service number on the tag so you can check your work records, should a tagged machine later return to...

You can still use that head, its just cooling passage to cooling passage. The integrity of the combustion part is not affected. No issue.

I'd suggest telling them since you don't carry "passenger liability insurance" for your ski you cant possibly let them ride with you, pesky lawsuits and all..then point them in the direction of a ski...

......First ski???
....for the family and tubing??
..already has 180 hours??

For starters, a supercharged ski is a terrible idea as a "first" ski.......unless you have money burning a hole in...

pre 2010 had some head cracking issues which seem to be limited to skis that ran in cooler waters. Pump bearings absolutely need to be replaced and upgraded without fail. And the ogura supercharger...

Hands down, the Ultra 150 was the fastest pre-2000 ski available on the market

Your budget is good for nothing except headache.

Realistically, for that budget, try to find something complete. Maybe a pair on a double trailer. Then sink some money LEARNING how to rebuild them...

I've seen quite a few of these that were heavily corroded. Of course, proper maintenance is the key to making anything last. But I think the issue is that this exhaust system requires more than...

The Ultra 150 was the fastest stock watercraft in 99 and 2000....The GPR was very close....

Again, I think you need to reevaluate your goal/budget. Are you mechanically inclined? Familiar at all with 2 strokes and how they function? Are you willing/capable to spend a LOT of time and money...

For a $1000 I would forget fast, you'll be lucky to find something that isn't a total POS and actually runs reliability enough where you're not scared to go a mile away from the dock.

Save up and...

The 11 year old OEM supercharger shaft with aftermarket compressor wheel failed at nearly 9000 RPM and 94 mph? That seems to be impressive more than disappointing.

OEM is handling what it's designed to do. If aftermarket can't keep up, you may need to ask what you're really trying to accomplish. Anyone running over 94MPH is not recreationally riding their ski,...

Did you by any chance hook up a garden hose when you attempted to start it? The procedure for the jetskis is to have the motor running before the water is turned on or there is a chance the hose can...

Sounds like she wants an actual boat.

My own riding is mostly not ocean, but we are often on unfamiliar waters and some of the lakes here are quite large. In addition to riding experience and the extra equipment we carry, a primary...
