U did good, probably have it done for 1500 whipping it out on the lake, im looking at one right now. U got Torque specs for that shaft cover right on the engine block i don't want to mess up

Could you please share who the Australian company was that you were saying could modify the crankshafts?

nice

Theres a 2015 spark in my town for 800 and comes with a trailer. Intrested on scooping it

Are you able to replace the crankshaft without taking the whole motor apart?

Do you suggest putting aftermarket shaft sleeve ( the collar ) 4:50

Replace the whole collar. Either job isn't a easy one.

Would it be possible to put a pin through the coupler and shaft? You would still get the freeplay unlike welding

I researched every possible direction it could be repaired & maintain reliability. This way was the only way. Remember to pin a crankshaft, your forced to drill threw hardened steel. That's probably not going to happen.

@@h2omechanic Thank you responding. The deal I am offered is not enough to take on this headache, which is very widespread.

how can i make sure that my pto is bad? i have a 2015 seadoo spark with only 40 hours never ridden in salt water. it was riding really good the whole time i rode it then parked it for a bit and next time i took it for a ride it was revving up and making a slight noise but not going over 8mph. i thought it sucked up some rocks but i took apart the jet and the Wear Ring and Impeller has no damage at all. it was full on gas. i have no idea why this happened if anyone has any knowledge on this please let me know

It's a sad and common issue. That's why I made this series of Videos. A cheap fix would be to buy the line-up tool & weld the shaft to the pto after you have set the line-up. At this point, your shaft & pto are junk, so welding is a cheap alternative, but most don't recommend it. I chose to do it correctly and it was very costly and time consuming.

What is the company that you could send the crank shaft to and they will send you the fixed one?

It was in Australia. I have a local guy doing mine. If he does it correctly, I'll ask to share his business name. That way anyone can send it to him here in the U.S. (east coast). I have everything, just waiting for the crank now.

@@gustavoperez7764 my crankshaft is still at the machine shop... My suggestion is that you buy an oem 2018 crankshaft. If you heat the fat end of the output shaft & use a 2 or 3 arm pulley puller you can actually pull off your old output shaft. Its not welded on, it's sweated on. So heating the end helps it swell & will pull off. I didn't know this before hand. But I've seen a Vid of someone who took it off that way.

Got crankshaft out will you give me details on place to get proper crank?

Watch the Vid I made on crankshaft repair. You can send it to my local cnc guy & he's setup to fix it. He's done many already. His info should be in the comments or videos description

I think this just happened on a 2015 spark , just about 40 hours , out no where doesn’t go above 8mph and after around 8mph just sound like the engine revs high but the it’s stripped and is spinning
