Seeing as I work at a Ski-Doo/Can-Am/SeaDoo (BRP), Kawasaki, Suzuki dealer in the Kawartha's, watch the age as parts become End Of Life AND if it's not a very common part that an aftermarket company makes/made, you're pooched.
2-stroke full synthetic oil stock is SO low I can't even order stock to replace what we sell. But lucky us we ordered well in advance of the current situation. Sliders, only OEM left available as the Dupont's are not available till after March 2022. Tracks, GOOD LUCK as there is a shortage there too from all brands! Belts too are probably going to be harder to get sooner than later.
Last fall we winterized 220 Seadoo's and this year over 450 units. That's how crazy the world has gone in the past 18/24 months. No stock, high demand, used selling for almost as much or more than new but no NEW to be had as it was all ordered, bought and paid for over 8 months ago for any product line.
I wish you the best of luck in your search but please keep in mind of age (lack of old parts) and a shortage on the newer sought after stuff.
