Service Tips
When replacing only half of your drive, upper or lower, it's important to service the other half to avoid damage to the replacement. The half that's not being replaced should be disassembled, cleaned, inspected and resealed before assembling the outdrive.
Core Value
There is no longer a core charge on the Mercruiser Alpha I uppers, lower units, or complete drives, so there's no need to send your old one 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.
