SEI Plunger Follower (Mercury Compatible)
The SEI Cam Follower, specifically designed for Mercury outboard motors, replaces the original OE# 89594A1 part. It is manufactured from heat-treated steel to enable gear changes in the gearbox, transmitting clutch movement between the forward/reverse gears and the shaft without wear.
Cam Follower Advantages and Features
- Precise Engagement: Components such as the clutch dog and shift cam ensure smooth and play-free gear changes.
- High Surface Hardness: Subjected to special carburizing heat treatment to make it resistant to friction and wear.
- OEM Tolerances: Manufactured to micro-tolerances that will not disrupt precise alignment within the gearbox.
