As far as I know all inboard ski boats are lh rotation except for older Natiques.You could look at the prop on the boat and that will tel you which way it rotates.

It,s posible the motor could be RH rotation,or could just be the wrong valve cover.I know when an inboard is in gear going foward the transmission is direct drive.The prop has letters stamped on it telling if it is LH or RH drive.

When in doubt, send a PM to Engine Nut. He knows everything in this area.
Edit: Ah, whatever. I just sent him a PM. He has been golden when we need him.Last edited by kaneboats; 03-14-2014 at 10:54 AM.

If you are rebuilding the engine and have it taken apart, you should be able to see if the engine uses a conventional timing chain or does it use timing gears. Typically right hand rotation engines used gears instead of chains so the cam and distributor would continue to turn the way it would on a standard rotation engine while the crankshaft turned clockwise.

I have a 99 Mobius - which is basically an Outback - and it has an Indmar 5.7L engine with standard rotation. If you have a PCM - maybe it is aftermarket? Wasn't Nautique using PCM for a while and they are opposite rotation - correct?
If you believe something to be true, it will be - in it's consequences.
