General Application / Compatibility
- These were removed from an actual Sterndrive Engineering SEI SE106 gearcase which is the replacement for MerCruiser Alpha One Gen 1 drives (1970-1990)... After having dealt with our fair share of SEI drives over the years, I would NOT recommend using these parts to replace parts inside of an actual OEM MerCruiser drive, nor would I put OEM MerCruiser parts in an SEI drive (With the exception of seals) If you need some actual OEM MerCruiser parts just look at our other listings.
