Common Concerns Answered
Will this thrust washer fit my engine?
Verify the specified inner diameter (1.5 inches), outer diameter (3.0 inches), and thickness (0.25 inches) against your engine's service manual or existing part to ensure precise compatibility. Consult our fitment data for specific model applications.
How does a thrust washer prevent engine damage?
The thrust washer absorbs and distributes the axial forces generated by the propeller, preventing these forces from directly impacting and damaging the crankshaft and main bearings. This ensures the longevity of your engine's rotating assembly.
Is the corrosion resistance sufficient for saltwater use?
Yes, the corrosion-resistant plating is specifically engineered to withstand harsh marine environments, including saltwater exposure, to ensure extended service life and prevent premature degradation.
