Impeller base gasket Alpha One Gen 2 question

[Franco_boater]

Hello my friends I hope you are doing well,
3 years ago ive replaced my impeller, now i want to check it, I ve found OEM gasket in my stock, its OEM Quicksilver but its different than Ive used in the past I think i have used newer one and now found older style.
I have this already installed on a boat:



Can I just use my spare one like this?:


Its alpha one gen 2 from 2005

Ciao

Yes either style works the lower one with two fiber gaskets is the older design upper one is currently what you get from merc

Wasn't there an OEM one recently that had the gaskets already attached to the base plate?

Could be the two pictures are the ones I’ve seen. Just installed one using the first kit he references when I winterized this year

When I was replacing impeller 1st time, I had plate with 2 gaskets already attached, but 3 years ago bought new OEM impeller with set like on pic # 1

Yes all of them work , not sure why merc changes design, would assume given how many impeller kits they make it is driven by manufacturing costs or material availability To whatever supplier they have at the moment.

either way i have used i think all three designs no issue or failures, the merc impellers last a long time. I just changed mine after 6 yrs , 240 hrs was in perfect shape. Changed my friends factory original was 11 years old also in perfect shape.
