As stated...

Looking for an Alpha One (gen 1) 1:50 ratio unit in nice condition cosmetically as well as mechanically.

It's got to come to Toronto so shipping might be an issue....Anybody have one kickin' around the shop???

woobs, I've got a Gen II in the shop that would probably work for you, but it's got a strange noise from the upper bearing and it's on the other end of the continent in Alabama. It's my spare drive and/or an emergency anchor.

For probably $1300 shipped you can get a brand-new SEI with a three-year warranty. Not sure how shipping to Canada works, maybe $1300 and a case of Moosehead. I would lean that direction before buying a basket case alpha, especially after all the work you put in your motor.

Do you really think the SEI's are okay?
I'll cost me only $1,500 + 13% tax....$ 1,695

And I can still sell my old 1:84...

I voted with my wallet. Just didn't make sense to rebuild the old Alpha (for more money) and get no warranty, and definitely didn't want to spend $3k on a new Mercruiser unit. Thus far I have been very happy. Returned it once to get a shift issue sorted out and I have nothing negative to say about the service I got from SEI. Overall very satisfied with the drive, and I have put a good bit of hard time on it over the last year. Running the good Merc gear lube and a drive shower, which I think helps with drive longevity.

Would I rather have a Bravo? Absolutely. Is it worth the $6k+ to me to convert? Heck no. Do some independent research and see what you come up with - I will give you one data point solidly in the SEI column.

Side by side Merc cannot compare to SEI, Merc is twice + the price with a "1" guarantee where as SEI is under 1/2 the price with a "3" guarantee. A NO BRAINER!

If you just want to change gear ratios, just buy an upper. The lowers are all the same. Might be cheaper to just change the gears in yours.

Great! I hope your experience with them is as positive as mine has been. I'd also order an extra installation kit, or at least the bellhousing gasket and o-rings. It sucks to tear the gasket during drive installation and then try and find one locally or have one shipped - ask me how I know... :embarasse

Also, if you don't have a drive stand you can slap one together with scrap lumber while you're waiting for the drive to ship. It makes life a LOT easier!
