Sea doo-657X piston size.

[Dpilot]

I've just removed the engine from a 94 XP, disassembled... Need one piston and sleeve.
The piston is ElKO (I know it's the OEM part), the size stamped on the inner side is 78-2+, I was trying to search with no luck...
Can someone tell me if that's a standard size or oversized piston, so I'll know what direction to go with the cylinder exchange?

That is stock size, If you are ordering from us than you will get a kit with half over pistons, we would need to know if the numbers on the cylinder end in 80 or 82. 82 is the X motor cylinders you should have.
