Good To Know

Q: Do I need to split the crankcase to install these seals? A: On most two-stroke PWC engines the crankshaft seals sit behind the cases, so crankcase separation is usually required for a proper install.

Q: How do I know the seals need replacing? A: Common signs include oil leaking near the crankcase, poor running from air leaks, or a bottom-end rebuild where seals are replaced as standard.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
