Good To Know

Q: How do I know the regulator is failing? A: Common signs include a battery that will not hold charge, dim lights, or erratic gauge readings. Testing charging voltage at the battery is the quickest check.

Q: Does this fit every SeaDoo listed? A: Fitment can vary by year and serial number within these model families. Confirm your machine's OEM part number matches 278000123 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.
