Service Tips
When replacing only the upper or lower, be sure to have the other half serviced as well. The other half should be disassembled, cleaned, inspected and resealed to ensure it doesn't damage the half you replaced. Warranty doesn't cover damage done by the other half of the drive.
Always use the correct gear oil and filling procedure listed in your manual.
Core Value
There is no longer a core charge on Mercruiser Alpha I stern drives, so there's no need to send your old unit back for credit.
Complete Drive Savings
Complete drive savings only apply when a complete drive is ordered. If both lower and upper are ordered separately at different times, full individual prices apply, even if they're ordered within a short period of time.
All units are shipped without oil! Be sure to use the proper oil and filling technique listed in your owner's/service manual.
