OMC stern drive ?

[Gordie Miller]

I know I should not have done this but.............I took in an old OMC stern drive to work on and I can't figure out EXACTLY what I've got. It's a 140 HP inline 4 cylinder, model #980703. I've got two OMC model reference books and neither one shows a match. They both have a ****load of 990 #'s. Anyway, customer thinks it's a 1977. It's on an old Hustler boat, square nose tri-hull built in McHenry IL. Any help sure would be appreciated. Thanks in advance!

Sounds like an electric shift short version, What do you need to know?

Mostly just the year at this point, if I know for sure at least I'll have a fighting chance using the right manual. I haven't really gotten into it yet. Put the battery on charge overnight, get started in the a.m. Customer got the boat from a neighbor for nothing, it supposedly hasn't been run in about 6 years. I'm just trying to see if it's even worth trying to make it run. She doesn't want to spend much $, obviously, the things not in too bad of condition. Told her I'd take a quick look and give her my opinion. Why is this not in the model reference book? Any idea?

ohh man
What I know about those is the drive sproket/coupler between the drive and main housing wears out in one season of use.... Used to do that every year as a teen ager for my grand pas Viking deck.
