Troubleshooting & FAQ

How do I find my engine's serial number to confirm fitment?

Your MerCruiser engine serial number is typically found on a metal plate or tag attached to the engine block, often near the starter or on the flywheel housing.

What is the difference between part 35-8M0067337 and 35-8M0231398?

Part number 35-8M0231398 is the latest version that supersedes and directly replaces the older 35-8M0067337. They are functionally identical and interchangeable.

How often should this fuel filter be replaced?

For optimal performance and engine protection, it is recommended to replace your water-separating fuel filter at least once per season or every 100 hours of operation, whichever comes first.

What are the signs of a clogged or failing diesel fuel filter?

Common symptoms include difficulty starting the engine, erratic idling, engine sputtering, a noticeable loss of power, or increased smoke from the exhaust.

Can I use this filter for a gasoline engine?

No. This filter is designed specifically for diesel fuel systems. Using it with gasoline can lead to filter failure and potential engine damage.
