I haven't been on here much this winter in regards to posting, but I have been reading alot. Anyway, I have a 1989 3.0L 4 cylinder Mecruiser and the out drive has been replaced with an SEI unit. Its time for a new raw water pump and I wanted to be sure which kit to purchase. Would the kit be the same as for the original Alpha......or something different? Thanks!

From what I can find they are the same. Found several selling impellers and they list them for both Alpha and SEI drives.

Just so all may know if asking the same question as I did, I purchased the Sierra 18-3320 raw water pump kit...it fit perfectly in the SEI drive.
