I totally agree, im just asking the questions to help sort out the rules. I see this from a different point of view from other people. I see it as how far can i go and still be legal. You need to write in the rules s/s style engines only, oem crankshaft. 800cc limit. That takes out aftermarket...

And Pumps ?? aftermarket pumps

What about the polaris engines, Or will you have to keep the stock engine for that hull

See all the 9mm stroker cranks turn up on the market. You actually would start getting to a decent bore stroke ratio

800cc stroker would still make great power. It would be a fun ski to ride as well

I'm very keen to hear of progress. I'm building my superjet right now

Its a guy in perth in australia that did that, im not sure he has run it at this stage.

Jb weld works very well

I used the stock steering cable. it lasted about 10 minutes

The new stator will make your ski a dyson. lol i think he meant idling on the trailer in the water

Huh ? What was the difference on the trailer

or spend time bending your prop, this is a good reason to have a nozzle with adjustable rings and a tacho. it makes it alot easier
