I'm looking at some OEM Bombardier pistons and rings now for $75 bucks for new, which seems like a good price for my next rebuild!! But how do they stack up against Wiseco ?? In the dirt bike world they're pretty dam good. I also had good LONG term luck with pro-X first hand. But I narrowed it down to OEM stuff or Wiseco?? For Sea doo top ends, what's your pick between the too?? Im good with WSM Stuff, never tried it and heard it's a hit or miss 50/50 review, so there OUT!!
 
OEM Pistons are hard to beat. When Wiseco's are used... the clearances are different.


BUT... if you expect a +20 year old crank to hold together... it won't. The new top-end will take out the old lower.
 
As the good Dr. said, the best are the OEM.
Wiseco's expand at a different rate because they are forged so the piston to cylinder clearance has to be set different than the stock specs or it will seize.
The WSM's are perfectly fine for a stock rebuild.
If you can get the OEM ones with rings for $75 it is the best way to go.
