2- 787 Challengers driving me nutts

Hey Racerxxx, That fuelly motor has the stock crank, pistons, flywheel and cyl., but carb motor- stator, and housing. Is there any power or other issues I would have running it that way (it does run).. Rock

I can't answer for sure, but...... I know back in the day Ski-Doo would use the same crank BUT would alter the position of the woodruff key depending on if it was a points ignition or Bosch polar-fire ignition--depending on what year the sled was(going back to the sleds in the mid/late 70 into the 80's). Say a '75 340 with points had a different crank than a '79 340 with a Bosch Polar-fire ignition, the crank would fit but the key way was say 45 degrees different. So I'm not 100% sure on your situation, but I would assume if you stuffed all the carb mag and stator in the carbed mag housing and it runs you might be good to go.

I'm also assuming you have carbed jugs on the engine?

The cylinders are the stock fuel injected ones (this is an early throttle body, not port injected). Seems to run fine out of the water. Guess the proof will be on the water run. I think my new call name should be "Sea-Doo-fus"!.. Rock

I am certified on OMC engines. I used twin 300's on my 25 foot combat boat. They were monsters. Ran unreal and BARKED when you were not in the water. Which was pretty often. Had to step up to neoprene water pumps as the rubber water pumps couldn't take the high revs when out of the water.

Ha, I'm a certified lunatic with crazy ideas!
