They used a rubber band in the past. They also did a timed slalom until 1993 but got rid of that because Superjets couldn't do it very well.

You can inspect the hull easily if it has original paint. If its been repainted then you cant tell how much damage has been coverer up. The pump is easy to inspect. The engine is always a consumable item, it could be very good or it could have an old rusty crank. Theres no way to know without...

Make sure to add a bypass between the engine and exhaust since all the cooling water goes there. The stock fitting on the head is threaded so its easy to add a barb there and into a new pisser.

Try some tooling cloth, it goes around corners easier than that thick stuff.

Sometimes water needs to stick to a surface, that is how tubbys work. Adding air will interrupt the boundary layer.

You can use a large hub impeller on the stock stator if you want. Adding a "mag" stator does not help as much as the prop. I have a 9-15 Solas YQ ,"large hub". It would need to be pitched down for best response although a low port big bore may be able to pull it. A larger nozzle will make...

A rear side outlet could interfere with the rear sponsons ability to work. It would be a safer bet to run the exhaust straight out the rear.

Wats it going on?

Make sure to use the large diameter exhaust hoses and muffler. You will also need a high pitched impeller for the 144 pump. It needs to turn no more than 6900rpm. Ideally install a 155 unit, that will perform much better. Expect a noticeable increase in acceleration and a slight increase in top...

Yea, it was hard the way I did it but works great. I saw video of an x2 race in the early 90s where a little guy was using a rearward inclined steering head. If I did it again I would make a composite box that would sit on the ski and mount a custom head to that then use a long standup cable...

My experience with a Seadoo mix is using a "low" pitched seadoo 580 prop in a kawasaki 650, it worked perfectly. I also know that it will take a really big snow engine to pull the typical seadoo prop up to 8000 rpm. His options will open greatly if he learns to bend blades or just use kawasaki...

Then he needs to adapt a Kawasaki shaft since ALL seadoo props are too tall. Ive used old 14-17 seadoo Scats in Kawasaki 650s and never could tell any difference.

If he wants to get up to 7800-8000rpm, a very flat impeller will be required for a 700cc engine. I know old seadoo props are almost identical to Kawasaki 650s but were generally higher pitched. I have found new Solas 9-15 and 11-16 concords for Kawasaki 750s are the flattest props available...

Any impeller and nozzle combo that matches the power curve of YOUR engine, simple as that. Probably not what he wants to hear.

Its easy to take the one dimensional view of engine size equaling a certain level of performance. It does for a given design but you need to know exactly what port height and pipe combination you want before money is thrown around. A 900 with a dry pipe can run as well as an 1100 with a B pipe.

Very low pitch 155 impellers are more difficult to find. You have a good chance of finding 144 stuff that will work good without needing modifications.

Originally the middle class was small with a few very rich and most very poor. It took massive deficit spending during WW2 to make the majority “middle class”. The demographic has been slowly reverting for a while now. Right now the government is borrowing 8 billion dollars a week and is...

I wonder if he looks like Rick Flair. WOO!

The bottom screw adjusters are for the idle mixture only and the top adjusters are for full throttle only. If the tops end up over 2 turns out then use a larger main jet. Its important to make sure its able to get on the pipe quickly, this can be a challenge with high port cylinders. If power...

L People don’t bother me much anymore. I always seem to get frustrated when a young person tries something without without giving it much focus. I tend to shame them for it.
