What drive did I just buy???

[SSTKO81]

Just got a steal of a deal on eBay for what I thought was an alpha drive, but now I look at it and I'm not sure... Check it out and let me know. It's eBay item 300606483146. I've got an 80s alpha1 and merc 140 in my boat now. So I just want to make sure it's all interchangeable. Any serial numbers I should be
looking for? Thanks guys.

Looks like you just bought your self an MC-1 which pre-dates your alpha. According to the auction, it is a V8 drive which has lower gearing than what is used with your 4 cylinder.... I would cross my fingers and hope the guy didn't already ship it to you, so you can ask him for a refund.

You need to know exactly what you're bidding on before you pull the trigger....

Yup, looks like an oldy. I hope you like it, because the listing says "No Returns Accepted"

You could probably sell it for more than the $191 paid, but the shipping cost must be way up there.

It will have the 1.65:1 gearing if it is original to the 898. If so, you can still use it but you need to drop the prop size 2 pitch. So if you use a 17p, drop it to a 15p and it will be close, not perfect......... Better than a broken drive I guess.

Re: What drive did I just buy???

is the gearing in the lower unit or the upper? I was planning on just using the lower portion. Are they not interchangable? Guess I'm SOL if not:facepalm: But like tpen said, maybe I can sell it for more than I paid... anyone need an MR-1???

If i continue to run my 4 blade 17p prop what would I be looking at? Too low rpm? I've got a 3 bld 19p but that's no improvement...

Gearing should be in the upper.

Gearing in the upper unit.

Just use the lower unit. But make sure to wash any debris out of the existing upper unit if the lower grenaded.
