Alpha One Impeller?????????

[acdc96]

I have a 1986-1987 Mercruiser V8 with a Alpha One Drive...
I need to buy a Impeller for it, IDK what one to buy?
I don't know what generation it is either?
Any help would be appreciated,
thanks in advance

Just to be sure that you get the right advice, can you provide the serial # of the drive?

If you don't need either housing, you need the impeller repair kit OEM PN 47- 89984Q 5 It includes the gaskets.
Same kit used from 1970 to 1990 MC-1 to Alpha I.
Next to the last page of the document below shows pictures of the kits.

Don't make your own gaskets!!!!

What's the history of the drive? you doing routine maintenance, changing from an overheat?

Routine maintenance... can get away with just the impeller and gaskets.... An overheat and I would replace housings.

All the part numbers are in Don's link in the post above^^^

I bought Quicksiver # 4696148A8 which includes the upper housing, the impeller and all the gaskets you need... and then some, from a Mercruiser Marine Dealer locally for $41.00.
