Your ski will be just like the neighbor kids honda civic with a loud muffler.

Try turning down the compression, timing, and rev limit to pump gas levels.

All the current 2 wheel carts place the ski above the wheels so they dont drag the tail and also for trailer/stand compatibility. They become an incredible PITA when trying to load a ski in rough water, they float so high that its a two person job. I am building a 3 or 4 wheel low boy wagon that...

A 62T cylinder shines once you find a low enough pitched impeller and bore your nozzle. There is a trade-off between response and power, the 61X cyl having better response, 62T making more power. Just about every impeller made is too much load for 701s, especially high port cylinders with pump...

The pros make use of the best technology at hand. Biggest problem for most everyone else is the price. If the ski in the video was a shortened R/N, hes doing fairly well with the $4000 that he has in the whole package.

And remember when a 155 pump was way too big, because the champs werent using them. I think a Yamaha 65U could get within 20LBS of an average twin with light weight exhaust parts.

Tripples are cheap power, just find one that will fit and anchor it well. OR spend mega bucks on a custom twin. Freestyle is totally subjective and people are just trying to impress each other. Its not only what you do but how you do it.

If a heavy hull with a big twin can do what you want then a lighter hull with a tripple will do the same thing. The industry makes its living selling custom engines, hulls, and accessories. Nobody in the business wants to see a junkyard tripple doing a backflip.

The pump load should be set around 7000. The limit must be above that, everyone I know sets it at 8000 without problems.

Pistons will stay very clean when they stay cool and there is plenty of oil. Freestyle engines usually have clean pistons, dark plugs, and oily sludge in the exhaust. Run the same engine in a couch and you will see more of the opposite because of being full throttle all of the time.

Yep.

I see nothing wrong with the color of the rods. I have found them to get brighter or darker with different brands of oil, Citgo will turn them purple. The main thing to look for is corrosion pits in all bearing areas. Wash the crank with your favorite petroleum solvent and do a careful...

Dont worry about it and go have fun. The industry has already become independent of Yamaha and Kawasaki. Engine bans are largely for new manufacture and wherever there are too many wealthy people living. The real killer of mass produced standups is in the fact that kids arent making enough money...

If the coupler is not wearing out then it would be better to shim the pump instead of adjusting the engine and bulkhead fitting.

All Kawasaki skis prior to the 1995 SXI had no bushings and would get loose after about one season. There were aftermarket nylon bushings available that would fix the problem.

A low pitched prop that makes maximum low speed thrust is best for everything except racing. You should be able to find a good used Impros modified 13/16 concord or a small hub Skat 12-17 swirl plenty cheap. They are almost, if not as good as the newer big hub impellers. A Hooker 9-15 is ok but...

The Solas big hub 12-18 is too much, the 9-15 hooker is a little less load. A pitched down small hub 13/17 concord is a better match.

Nice skis are few and far between these days, plus the Superjet fever is running up prices. It will still take at least another $2000 to make it worth riding.

The job is not too bad as long as you can specialize in one area or brand, that is how a mechanic makes more money for less effort. It is stressful having an endless stream of new problems to solve for a fixed amount of money. The fact that owners dont like paying for something intangible like...
