Easy-to-Miss Differences
- This is an aftermarket replacement. Mercury 8M0225510 is a reference number, not a JLM Marine MPN.
- Application is tied to the engine serial number; the published family is Mercury Racing 500R V8 rather than every Mercury outboard.
- A gear oil pump is listed in the kit, but engine oil and gear oil are purchased separately.
- The current package list includes both 830749.0 and 830749 lower unit drain gasket entries; retain each listing line when staging the service parts.
JLM Marine Advantage
More than 20 years of marine-parts manufacturing experience. This high-quality aftermarket replacement is engineered to meet or exceed applicable OEM specifications. Every unit is 100% inspected before release.
- Factory-direct pricing
- If the return is due to our mistake (incorrect or defective item), we will cover the return shipping cost and issue a full refund.
- Technical support from the people who make the parts
Aftermarket product: Not a genuine Mercury part. Brand names and part numbers identify compatible applications only.
Installation Notes
- Use the engine serial number and the current service manual to select the required service procedure.
- Stage the filters, O-rings, drain gaskets, V-belt, and pump before beginning work.
- Use separately purchased lubricants, then follow the manual for all tightening and belt-tension requirements.
- After service, inspect the work area for leaks and record the engine hours and service date.
