What This Part Does
The rod eye pin cap fits over the rod eye pin assembly, helping retain the pin and protect the connection point from vibration, debris, and mechanical wear during engine operation.
Parts Desk Insights
Best use case: This cap is best suited to replacing a missing or worn rod eye pin cap on select Mercury Verado and Racing outboard engines, where it keeps the pin assembly retained and protected during operation.
Most common mistake: Ordering by engine horsepower or appearance alone. Pin caps vary by engine model, mounting configuration, and serial number range, so matching the part by engine serial number avoids ordering the wrong cap.
Sizing and fitment: If you are servicing a Verado or Racing outboard, confirm your engine model and serial number range before ordering, since hardware of this type is not interchangeable across all engines.
