Good To Know

Q: Should this gasket be replaced every time the throttle body is removed? A: Yes, a gasket that has been compressed or exposed to heat should be swapped for a fresh one whenever the throttle body is taken off to keep the seal reliable.

Q: Does this fit both the Utopia and SE 1503 models? A: It is listed for Utopia and SE 1503 watercraft, but serial number and model year differences can affect fitment, so confirm against your machine before ordering.

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