    That is an electric shift dealio, parts are fun to find, but there are some out there...I have the manuals for them...FWIW, the later model (1976 and later) have the same upper gearcases, but only made one height case, the electric had high profile and low profile...

    The water pupmp shaft splines are the weak link, very fine spline count would wear out and slip, the problem there is the upper gear shaft needs to be replaced at the same time....

    I will see if I have a back up manual.

    Edit;, I would look for the superior later mechanical shift outdrive and switch it up, you will need from the transom assembly down, can be found on the cheap nowadays, parts are only slightly easier to find, but can be done.

    When you say springs, I am assuming the lower is toast?

    The lowers are pretty straight forward, the spring believe it or no, is what drives the propshaft, the coils are actually magnets the energize causing the spring to clinch down on the knurled hub and that drives the shaft, crudely simple, but they worked...

    I can help if needed, I will be at the shop sometime Monday and I will see if I have a spare manual...I used to be able to build a lower in about 4 hours with new seals, but that was when I was doing about 50 or so a year...

    I will let you know.

    Still say upgrade if you and he have the opportunity...

    I have an electric shift lower gearcase (worked OK but uninspected) in my warehouse. I also have OMC Manuals & the required special tool set for the 'Stringer Mount' drives but I am in Celina, OH. My OMC parts inventory is fairly extensive for equipment that age. This appears to be the low-profile (shorter) upper gearcase.I'll be glad to help you with some long-distance advice...

    He does have the low profile...

    Are you a shop or just a hobbyist with a hording problem?

    Do you sell parts I guess is where I'm coming from, always looking for an option.

    Be careful posting up stuff for sale BTW, that sort of thing is changing to a chargeable service...

    Thanks!

    Grew up in the boat business...Grandpa & Dad started a marina in 1955. I stopped working in the family business in 1989. I do have a shop but I limit my marine repairs to a few well established local customers, friends, & family of course. I am a career Fireman/Paramedic for my community. The shop is used primarily for our Inboard race boat(s) now & a Hondo V-drive project. The gearcase is left from a repair job I did last year. We needed an upper housing with internals so I found an acquaintance who had a complete drive. Thought I might be able to help out...not wanting to aggravate anybody over here with my offer of assistance/parts. Give me a call at your convenience.

    I bought an OMC manual on CDRom off eBay really cheap before going through my electric shift last year. It was like 5.00 plus shipping. Not sure about posting ebay links here, so pm me or do a search on evilBay for yourself if you like. It has been real handy to have.

    Nothing sinks faster than a OMC puffer drive with a split bellows! What is even more awesome is when the stringers rot out and the whole motor/drive assembly climbs in the boat on hole shot before it plunges to davey jones locker. I won't touch one of those with Nancy Pelosi's dick anymore.

    Around here the muskrats have been responsible for making some former boat owners very unhappy...OMC used to make a 'Rat Guard' for these for around a hundred bucks. Pretty inexpensive compared to the cost of hoisting the boat off the bottom & drying out the interior & mechanicals.

    I have run a OMC stringer drive for about 15 years in my family boat. They are a real pile of SHIT!!!! Mine has a throttle with push buttons for forward-neutral and reverse. The first time I put the boat in the water with a boat full of people I had it full throttle and I hit the reverse button......

    I can say I had eveybodys attention after that little TRICK!!!!!

    Those splines were made for like a garden tractor and they put them in a boat. I have had mine apart a few times.

    Im kinda surprised none of you guys mentioned the "BALL GEARS" The wonderful set-up that they are.
