Using an isolated-base solenoid in a grounded-base application (or vice versa) will cause electrical faults. Confirm your existing solenoid’s base type before ordering. This solenoid is most commonly needed on older Mercury outboards and MerCruiser stern drives from the 1970s through 1980s that use the Mercury 65057 series.
