You have Numbers off the leg ? Electric shift legs " Mercs " ??

Ayuh,....

You're going to find that the old electric shifts are becoming Antique,+ I believe they are no longer supported by Mercruiser...

If you go up to the "Adults Only" sticky at the top of the forum,+ download manual #1,...
I believe the electric shifts are covered in it....

Don will be by shortly,+ I'm sure he has a better idea of your Options...

Thats the one with the clutch in the drive?

Never saw one in person myself.

Assuming you are talking about the electrical unit that mounts on the inner transom that shifts the 1 drives, about the only thing I can say is make sure you have power to the unit. I haven't seen or worked on one of those units in 10 or 12 years, and have never seen anything in any manual on it. SM #4 does have a troubleshooting chart, but no drawings or wiring diagrams to go with it.

thanks for the responses,

the shift is on a 1968 bertram hardtop built by internatial marine in Australia
running duel 165 mercrusers

there is power and earth running to a bank of 8 relays, which the shift switches are wired two, the then send wire down to the actuaters on the transum which then pull push the shifting cable, there is also a rev limiter which stops the shift if not ideling. still think it is a wire loose or off ???

Well, the 165's didn't come out until 1970, and since you have a 68 boat, it's really hard to say what was changed to what in the past 40 years by previous owners. Got some pictures of your setup?

problem fixed, there were a couple of faulty earth leads which stoped the units working.
