62 Electramatic LU rebuild

[Altstuder]

I’m about to go down a rabbit hole. I’ve got a 62 Super Seahorse 75hp that won’t go into forward gear. I’m new to boats and I’m not an experience mechanic but I’ve got a little experience working on my cars and motorcycles over the years. The forward coil is reading about 7.5ohms compared to the reverse at 8.6ohms and it is putting some drag on the prop but not locking it. I’m going to tear this thing down. I’m waiting on the Clymer manual. Any general tips on things that I should be replacing or inspecting while I’m in there? Is there a rebuild kit for this unit with seals and gaskets etc? Are there any specialized pullers I need? I want to get the parts coming asap. Thanks

Find a service manual. (OEM parts manuals are sometimes enough -- check for those as well.)

Most important bit of advice I can think of: There are two nuts on the studs holding the upper and lower gearcases together. Do NOT have it in the conventional "pickle fork" holder when you remove those nuts. If you do, the lower section may fall away and yank the coil wires in two. Instead have it laying flat on it's side on the bench. Don't ask me how I know. An expensive $$$ mistake.

Yes there are some special tools. Mainly for removing and reinstalling the front coil and bearing. You can get by without them but they certainly do help.

EDIT: About those sections falling apart. Even worse, a LOT of them you cannot even get apart. Sometimes you have to take them apart with a hacksaw. Maybe I should say usually, if it has been used in salt water.

Thanks for the advice.
