Motor failed with about 4hrs on it, couldn't figure it out until I started cleaning up around the holes and saw how thin one area was. I then noticed some epoxy on the other cylinder in the same area, checked other motor and it had epoxy in the area that had failed on the 1st motor. Smeone...

I can design dome too, never had deto on any of my motors Get you 1200 code later EJ 225hp '00-'04, 2nd last model on pg12 of Wiseco Marine catalog

1200 uses 98mm pistons, can get you code off the top if you want. There are also Johnson Evinrude outboard pistons in that size in the Wiseco catalog, not sure about crown and pin heights.

Wax Piston size?

Still waiting for the rest of my stuff:wizard:

What size piston you looking at?

Wax, did you get TSR? Let me know if you need help on design. B-pipe no good as manifold too small(area equal to a 48mm circle), need something with area of about a 55mm circle perhaps bigger depending on exh port size.

What impeller sizes are you running and can your ski flatwater backflip?

What nozzle size is best for a 144mm mag pump in a freestyle ski?

Direct fuel injection with oil fed through crank

The stuff not sent are all off the shelf things. He gave me shipping dates even though motors had not even been started on(found the truth out from Chris). Portings specs are off the 2 motors I have. TSR Software is the best software available for simulating modifications on 2-strokes

Yes, for about 10yrs now.

Those specs are off the motors I received, genII, I have seen pics of the genI When I enquired about getting the motors, he said 6-8 weeks, 26 weeks later I only have half of the goods I ordered and the domes are wrong. We have shows we have committed to and this is cutting down our practice...

3 businesses Even if I designed this on only weekends, I think you would have it a year before a wdk motor.

500 motox pistons too small. BUT Evinrude Johnson 225hp pistons = +/-97.75mm std, oversizes available

After this ordeal I am thinking of having my own cylinders machined and will give the design to whoever wants it. I am thinking of checking out the availability of pistons for the old 500cc motox bikes, should be about the right size.

He doesn't return email or messages. Best time I could get hold of him on the cellphone was 12pm PST. Good-luck. That pics is from 2006 Gravity Games in Australia, have discussed with them having Jetski Freestyle as an event in 2008.

With relatively minor porting the gen2 motor can give 174hp @ 4850rpm, with better bottom-end, more than that will require powervalve mods and some epoxy work.

Time is one thing, being told total BS when you phone is another. If there a hassle, inform the customer, don't duck and dive and use their money for dveloping other products.So don't hold your breathe for the fuel injection system he is supposed to launch at Havasu.

Time, I own 3 businesses and none of them use a cnc machine
