CHOOSE YOUR SCHEMATICS
PLEASE NOTE: Most MerCruiser and Mercury part numbers start with a category code, then a dash. Be sure to enter the category code when looking for part numbers. They are listed in the schematics in the first (left) column. Example: 32-858620A12.
These schematics are for specific serial number engine models. While many Cummins engines share the same part numbers not all engines within a family use exactly the same parts, please contact with the engine serial number to verify.
