Hello, I have a 1985 350 with Alpha 1 gen 1 outdrive, all original. I am looking to replace the impeller on the out drive. Anyone have a diagram/part number? Also is replacing the Gen 1 same as replace the alpha Gen 2? I am looking on how to video just for clarification before i start. Any help would be great!

The gen 1 & gen2 waterpumps are different the sierra part # is 18-3320 it is a complete kit & is pretty straight forward to replace just dont forget the o ring on the case to seal the lube tube between the upper & lower cases, & replace the lower half of the pump cause the seals can leak also make sure you use the right o ring on the lower pump. I believe their are instructions in the box or go buy a clymer manual. Randy

Thank you for the reply. Thank you very much for the part number. It does seem easy to do, all videos I have seen are for Gen 2, but I think splitting the outdrive is the same for both Gen 1 and 2. Parts are different but I think it is easy enough to figure out.
