The outlet pipe should be close enough to the bottom to vacuum out water at full throttle. This concept is lost in most aftermarket boxes, they tend to hold water and still make a lot of noise. I would install a small drain on any box that didnt dry out quickly. I think modifying one of the...
No, not all the same. Stihl Ultra has been found (by the US Airforce) to be the very best oil tested to date for their small drones. Redline came in second.
The best argument for cheap oil for freeride standups is in the way they are operated. Most of our time is spent running at low power levels with very rich carb settings. We also tend to drown our engines occasionally and almost nobody does a lengthy blowing/drying out before heading home. Cheap...
Look closer, the keel edges soften ahead of the pump. This gives the hull more lateral grip ahead of the center of gravity making it want to hunt, especially in smooth water.
You can reduce the S/N nose hunting by adding material to the keel ahead of the pump so that its flat instead of rounded. I absolutely hated Superjets until I did this mod.
Jetskis have become a sport for wealthy participants like boat racing and aviation. Kawasaki did well to create a new scene that was affordable enough for many kids of the day. Now it is impossible to do well without spending a lot of money. This situation is made more difficult because it takes...
I have dissolved a dead enhancer in methylene chloride. It has two boards with everything spread out. Good luck removing the urethane encasement without ruining many of the electrical components. A modified stock box is fine, no need to make it adjustable. Just replace the 91 or 100 ohm resistor...
You will know if your pole is too long or plate too short when the ski is tipping backwards too often at slow speeds. Superjets don't suffer from this until the rider gets big. A "D" cut stock plate has the effect of shortening the hull slightly but also makes the hull pivot quicker in low speed...
Jet skis have always had very high turnover, mainly because of the age of the participants. Nobody comes back later in life because its not fun when you get too fat. It doesnt matter what anyone else is doing unless you are in the business or must be part of a scene. You are in the sport as long...
Why did they choose a 5205 over a 6205? Probably because the double row can handle much higher axial load than the single, or maybe they had a lot of extras laying around.
The snow machine runs at higher rpm than a watercraft pump can use. An extreme example is a 125cc bike can make nearly 40hp where a 250 is only in the 50s. Double the CCs but only 50% more HP. The difference is operating rpm.
