Serial Number Fitment
Confirm horsepower, cylinder configuration and engine serial number before ordering. Verado production spans several generations, and serial number is the safest way to confirm belt fitment.
When to Replace
Replace the belt if it shows cracking, glazing, fraying, damaged ribs, excessive wear or slipping. Inspect it during scheduled Verado maintenance and replace it whenever its condition is questionable.
Installation Notes
- Record the original belt routing before removal.
- Inspect the belt tensioner, idler surfaces and alternator pulley while the belt is off.
- Make sure every rib is seated correctly before starting the engine.

Parts Desk Insights
Best use case: Scheduled Verado maintenance, or replacing a belt that shows cracking, glazing or slipping on an L4 or L6 Verado.
Most common mistake: Ordering by horsepower alone. Verado engines with the same horsepower span several generations, so the serial number matters. It is also easy to overlook a worn tensioner or pulley, which shortens the life of a new belt.
Sizing and fitment: If you are matching an engine that originally called for 880566Q14, 8M0232583 is the current Mercury replacement. Confirm your serial number against the ranges above before ordering.
