100HP Johnson Hydro Shift

[dive bird]

Hello,<br /><br />I realize this is a frequently covered topic, but I did not find the solution in the discussion board. I have a 1971 100HP Hydro Electric Shift. 100ESL71C<br /><br />Currently, the unit is stuck in forward at all times making boating a little difficult. I have the proper C grade LU oil, and I was wondering if anyone had advice?<br /><br />Also, the "shift box" was frequently referred to and I am not aware of the location or purpose. Any and all advice is welcome<br /><br />Thank you,<br />Dive Bird

Hi there dive bird. This topic has been covered extensively in the Johnson Evinrude board. Search for Hydro-Electric shift in that board and you will find detailed instructions on how to proceed. Good luck.

Re: 100HP Johnson Hydro Shift

The "shift box" is part of the controls for that motor. Do you not have a three-button control unit? Did you acquire this outboard with no controls at all?<br /><br />If so, you're going to need that. It's possible to rewire the thing to bypass that switch, but you'll need a service manual to sort it out.
