If the plastic elbow is below the waterline or if the pinhole gets clogged the ski will sink in a couple of hours.

The pistons are clean because the pilots are very rich and you are spending a lot of time in that throttle range. If you spend more than a few seconds at full throttle the top screw/main jet should be power tuned rich of peak rpm and then the pilot jet tuned for best throttle response. Your...

Plus you can lower the rev limit, that will make your crank last longer.

Boeing sent the good jobs abroad, what did you expect? The only place that the US has for undesirables is prison. That system works great in the south but the northwest needs to get in touch with reality. What is Mississippi? Its the most incarcerated place per capita in the entire world!

Try a larger nozzle and bend the impeller until max thrust is obtained.

You will seldom ever have "enough" power. It will cost $2-3000 To make a 701-760 good, and an additional $3000 for a "better" aftermarket large bore cylinder. From there it gets even more $$$ for the "best" stroker setup. Then you need a short hull in order to get it all out of the water.

The ski is old and the previous owner probably wont tell you how long he let it sit full of water after he sank it. So, take the whole engine apart and clean, inspect, and reassemble. Use new OEM crank seals. Replace the crank if has corrosion damage. The cylinder can be bored a little without...

You may not have fit the profile of the average new car buyer. Im sure I dont either and they would be correct since I dont buy new vehicles.

I know one guy that went to a dealer and left empty handed since everything was overpriced. He did better ordering a truck from the ford website, just has to wait for it. Times are unusually good right now with inflation spiking to 40 year highs. The federal reserve overdid their covid relief...

They can be a slip fit as long as the pin is hard enough.

I wonder if this project was primarily to do something with the 300sx hull, or the 900 engine. It looks like it began with very little planning.

Yamaha filled them with foam sponge.

Threre wont be as much tuning effect so its better to design a better flowing downstream. This is what Yamaha did on their old 1100-1200s.

You didnt fix all the leaks!

It is the most cost effective way to make a part. A cheap B pipe copy is what consumers want, somebody finally made it happen. Some day a container full of cheap AM hulls may show up.

Loctite will soften with heat. Fasteners will come right out of aluminum around 250 degrees.

Thankfully our Solas products are pretty good. The main problem with innovation is being able to sell what you creat. All the basic technology comes from government funded labs. Anything that is popular will tend to be junk because it’s sold mostly to the masses who don’t know any better.

It looks like most skis are in need of rescue from their owners!

They should be RTR. I say “should” because of Kawasaki’s crappy quality so check the bore first.
