Item Details
- Removed from a 1970's MerCruiser Alpha One GM 4.1L 165hp 250CID
- Used from 1968-1979 on virtually all OMC Stringer & Mercruiser 165hp sterndrive power plants. (both companies used the same GM blocks, but OMC used bolts rather than studs at the end of the crankshaft to hold the couplers on)

MerCruiser Part Number 430-3161
- Timing Gear 43-46745
- GM part # 3891590
- Yours should looks just like this.
- This was removed from a running engine.
- Some minor surface rust on this in some areas of the cast part (visible in pictures) but this is a very nice camshaft & I don't think you will be disappointed.
- If you are unsure if this will work for you, just ask.
- Purchase with confidence!
