I have a late 70s/ early 80s omc sterndrive and the switch in my throttle control box is shot and finding the same one is proving to be difficult... especially in Canada. Can I use any electric shift control box instead? Thanks
OMC electric shift control boxes were used on outboards as well and were in production starting in the early 60s. Some had push button shift also. If you find one with the ignition switch mounted on it that can be also used.
Out board switches do not have a neutral start lock out but can be used, You will just have to be careful not to start the boat while it is in gear.
The outboard control boxes that came with the early model thru hub exhaust sometime from 69- 71 were electric shift but will not work on an OMC stern drive.
If you find a switch or used box check the switch with an ohm meter, purple or red is the supply green for go and blue for back up and if there are 2 extra wires those are the neutral lock out.
Can you post a picture of your control box?
If your control unit is identical to the one in your first link , then you definitely have an electric shift , as I had the exact one for my electric shift .
your second link is for a mechanical shifting unit , no good to you .
take a pic of your outdrive so there is no guessing
I didn't have 12V in forward or reverse. But if I hooked it back up to the toggle switch I did get 12V
It wont let me upload the pictures I took so I added them to Google drive. Hopefully that works to view them. Here is the link. I also added pictures of an evinrude control box that I have taken apart wondering if it will work
Does the exhaust come out the center of the propeller , yes or no ?-----Is there a big black plastic cap that holds the pin and the propeller on the propshaft ??
He has an electric shift and they all had the black plastic cover that retained the drive pin. There never was a through hub electric shift that was a stern drive model.
