Which lower unit will work with Merc 170?

[Hardo]

I have a 1886 searay monaco 187/185, with a mercruiser 170 and I think
an alpha 1 or gen 1 - I can't remember, anyhow the lower unit of the outdrive has a hole (roadrash) on front of prop housing; I've been calling it the 'pumpkin. Anyhow, which lower unit do I need to order for this?

-Also, how long does it take to ship out (I'm in ID) and what are typical shipping costs?

If you have a 1986 you would need our 90-106-02 lower unit. We ship within 24 hours of an order being placed. Shipping to Idaho is $69.00 for a lower.

That's it? Just order the lower unit you mentioned? No gears or other additional items etc.?

If you have a 1986 boat and sterndrive and require only the lower unit you need our 90-106-02. The lower comes complete ready to bolt to your upper. You can reuse your old mounting hardware or you can purchase an installation kit from us, part number 90-106-03K.
