Engineered as an upgrade for Sea-Doo stock gaskets, this OULI gasket combats saltwater decay, housing bending, oil leakage and accidental water ingress.

It builds a rugged impermeable seal across the crankcase and flywheel/timing cover, shielding internal components from rust buildup, salt residue and grinding wear.

It keeps lubrication systems intact and safeguards engine integrity in harsh marine surroundings, running steadily for everyday watercraft use and high-speed water sports.

Manufactured in line with standard OEM requirements, it supports effortless DIY swap during regular servicing, cutting downtime and maintenance costs while boosting the long-term durability of the 4-TEC engine unit.
