Thanks to those who helped me in the old thread from 2017, lol. Been a while since I worked on this thing since I had such a hard time getting the paperwork from the previous owner. It has the 717 engine in it.
Since my last post, here are the latest findings:
1- The wear ring has completely disintegrated, so I am ordering a new one.
2 - Replacing the fuel lines with 1/4" as suggested.
3 - I let the cylinder sit with 2 stroke oil for a few days, then cranked unit over. I am getting 95 psi, using the recommended SeaDoo manual and youtube videos on compression testing. With a new battery, it cranks over fine. When I put both plugs in the starter clicks and struggles to turn the engine over; even if bypassing the solenoid so I figure the impeller is stuck (possibly plastic pieces lodged in jet drive or the starter needs to be replaced. Thoughts?
4- Worse case, I will end up replacing the rings and hone the cylinders if still in spec
5- Didn't replace the oil tank, added extra tubing with new oil to recirculate and will make sure the new owner is aware of the option.
6- completely washed and degreased inside compartments
I don't have a lot of info on why it was stopped being used, so not even sure if it was just put in storage or if it was having issues. I haven't started it via gas since the cranking issue is happening. It should start even with the low compression (apparently 120 -150 psi is the norm with good rings); just don't want to cause any damage inadvertently in case it's a jet drive or impeller issue.
I now have a 2001 Yamaha that I am rebuilding (injection lines came off of carbs; common issue apparently), so once I have this HX squared away it will be sold. What are these things going for in clean shape, which this one is since it's been in storage since 2008? Online, the prices are all over the place.
TIA....
