Hi guys, yes it works. The only failure I had with it was tearing the splines out of a prop when I was flipping it off a knee high boat wake a few years back. Currently I have the hull in the middle of reshaping. The engine doesn’t shake bad at all, it’s just like a normal ski. Shakes less than...

Just an update. I fired the ski up and with the balance shaft out it shakes like a normal engine. Just like my stock 750 does.. And it revs super fast!

Also whipped up some pisser fittings. Just need to paint em and glue them in

Engine is in the ski. I just need a new battery lol

Here is where it sits now. Just about ready :)

The counter balance shaft is there to deaden vibration, being that the engine was orginally for a sit down ski. The crank will be fine without it. A unbalanced crank is a unbalanced crank. It will eat bearings with or without a balance shaft. Make sense? All the weight reduction on the rotating...

Yup, okuma mu400va 5 axis. Its my favorite machine at work

Chopped the flywheel down too!!!

Just whipped these up

After i run it i will know if any issues pop up. But so far so good. Here is a pic of me chopping the stock pto down to nothing and my hull all painted up. Next is to chop the flywheel up and the engine goes back in!! Ive pulled over 25 pounds off the engine alone. And 18 of that was rotating...

No turning back now, counter balance shaft delete is underway!!!

The first ride was a lot of fun! Its scary fast! I can see why there were so many of these swaps in race skis. The hull feels great, lots of pop. Easy to ride and predictable! I just need to make it lighter and play with prop/pump set ups

Thanks for the offer, but i'm a machinist/tool and die maker by trade. I got it ;)

Its too cold to ride up here now. The next thing i will be doing is pulling the counter balance shaft out of the engine, cutting the pto and flywheel and deleting anything else to save weight. The ski rips but is almost as heavy as a stock 750sx.. I know i wont have a problem getting rid of at...

Yup! We'll see how it goes, but i can say my bros 300sx with the 155seadoo pump and a stock 750 motor can flip a kneehigh wake. So this should be a big improvement, wider hull and a lot more power to push the bigger pump. I will be swapping back and forth between a stock seadoo 155 and a skat...
