Driveshaft housing oil seals and driver tool help

[TheRussian]

Good day,

I am in the process of resealing an Alpha One Gen 2 outdrive. The current drive has 2 separate oil seals around the driveshaft. The seal kit in my possession has a single, thicker seal with the lip (spring) on both sides. I am OK to use the single seal instead of 2 separate seals? It seams reasonable to me but I want to double check.

Also, the driver tool for these seals is quite expensive (91-817570). Does anyone have a workaround?

Thanks!

i bought a seal and bearing cup driver set from Harbor Freight worked great had an assortment of seal and bearing cup drivers.

look at parts diagram in this link there is a serial number split for one seal vs two- part #5. Would only assume that if the later siungel seal worked for all they would supercede it not offer 2 but maybe mercruiser tech support can confirm that

Thanks. I was hoping that a bearing driver would work.

Regarding the seals, my outdrive is 93/94 with 2 seals. It just appears that a single seal that has the lip with a spring on both sides would/should theoretically work, but I would like to confirm that.

Just did this same job on my Gen2. New kits have a single double lip seal, opposed to 2 single lip seals. Install it with the slight flange facing down towards the prop and use some liquid gasket on the edges. Installed mine with a socket, forgot the exact size, worked great.

Amazing, thanks. I was thinking of using the double seal and see how the pressure test holds up.
