Perfect for your Alpha
This kit had every single piece needed for my Alpha water pump - and many I didn't need. I guess it fits basically all the different versions out there. I remember when the single kits cost more and had much less. This is a good high-quality alternative. Stock up on them now - you'll need one eventually.

Great bang for your buck!
Swapped out my old impeller and this helped fix my overheating issue. Super high quality, fit like a glove. If you know what you’re doing it’ll take you an hour tops. Super solid for the price! Fit into my 1990 alpha one gen 1 outdrive on my 4.3 Mercruiser.
