Important Fitment Note
Pro Marine 24564P is intended for select Mercury Verado 225, 250, 275, and 300 HP Inline 6 (L6) 4-stroke outboards.
Mercury produced multiple Verado engine configurations, and gasket compatibility varies by engine family and serial number. Not all Verado engines use the same cylinder head gasket.
This gasket is for the compatible 2.6L Inline 6 Verado applications. It should not be assumed to fit Mercury Verado 4-cylinder engines, V6 engines, V8 engines, V10 engines, or other Verado configurations.
Always confirm your complete engine serial number and the required Mercury OEM gasket number before ordering.
Compatible Mercury Verado Applications
Pro Marine 24564P fits select Mercury Verado 225-300 HP Inline 6 4-stroke outboard engines within the listed serial number ranges.
| Engine Family | Horsepower | Configuration |
|---|---|---|
| Mercury Verado L6 | 225 HP | 2.6L Inline 6, 4-Stroke |
| Mercury Verado L6 | 250 HP | 2.6L Inline 6, 4-Stroke |
| Mercury Verado L6 | 275 HP | 2.6L Inline 6, 4-Stroke |

Understanding Mercury Verado Serial Number Fitment
Mercury Verado L6 outboards were produced in multiple horsepower configurations and production series. Some serial number ranges overlap because they represent different engine variants.
The ranges above are supplied catalog applications and should be checked against the exact engine horsepower and serial number. A matching serial range alone does not establish compatibility with every Verado model.
