Serial Number Fitment Notice
Volvo Penta fitment can vary by drive model, shaft arrangement, and production break. Confirm part number 851407 against your exact engine or drive serial number before ordering to ensure the correct sealing ring for your application. Volvo Penta's engine and drive identification tools are the best final check for genuine parts selection.
When This Part Needs Replacement
Replace this sealing ring when the original ring is leaking, hardened, cut, flattened, worn, or disturbed during propeller shaft or gear-housing service. It is also a smart replacement item any time the surrounding assembly is apart, since seal performance is critical to keeping water out and lubricant in.
Installation Notes
Install only after confirming the exact application by serial number. Inspect the shaft and sealing surfaces for wear, scoring, or corrosion before fitting the new ring, and follow the correct Volvo Penta service procedure for your specific drive. On applications where two rings are specified, replace them as a matched set during service.
Alternate/Superseded Part Numbers
Current sources reviewed identify 851407 as an active Volvo Penta genuine part number. Aftermarket listings may show replacement-style references such as 851407-R, but genuine-order verification should still be based on Volvo Penta 851407 and your serial number.
Parts Desk Insight
Sealing rings like 851407 are small parts that play a big role in sterndrive reliability. When a drive is already apart, replacing the seal instead of reusing an older ring can help prevent repeat labor and protect the gearcase from moisture intrusion. On older Volvo Penta DP and SP families especially, careful serial-number matching matters because several similar-looking seals are used across nearby drive generations.
