How to bench test OMC Electric Shift Stinger?

[hockey4chr]

OK... so i have searched High and Low for this answer and not even the book i have says how to test on a bench.

My problem is... The out drive was working 100% ok (except water pump) So i took it apart, replaced the water pump and put everything back together. When i went to put the out drive back on the boat before i bolted the two "c" clamps on to hold the outdrive i put the shift wire through the housing. And due to me just eating a tub of butter (jk) the outdrive fell but caught on the shift wire. I went to place it on the boat thinking nothing happened but ever since then i cant shift into gears.

How do you bench test the wires?? I read to put 12volts to them but before i do that i wanted to get it in detail on how to do it properly.

Thank you in advance for your comments.


picture just for reference. I dont have one of the upper and lower separated. Will get one if needed.

Read through MY LEARNING EXPERIENCE and see if that helps you check it out.

Thank you for that. I will look at this first thing tomorrow morning and i will try and get the OHMS and make sure that im getting 12v at the intermediate drive hook up to the controls.

Thanks i will let you know what i find.

One wire is forward and one wire is reverse. Ground is just the drive itself. If you don't have a good ground between the drive and the intermediate housing and you greased up the trunions well, you might have a ground issue especially if both forward and reverse don't work. There should be a stainless steel cable between the drive and the intermediate housing...is there one?

Just out of curiosity, what did you find was the issue with your shifting?

Well ... I'm not 100% sure.

The rrrrrrrrest of the story is: I was getting good energy to the knives and everything seemed as though it should work. Intermittently, I wound up getting into gear but it would fail rather soon. My best guess was a short in the shift wires, but I took it to the shop as I mentioned in that other thread.

I posted a little bit about it on the forum, but didn't wanna' bad mouth the shop. The tech wound up cutting my shift wires and pulling my lower off. He told me my upper was locked up (bringing about THIS thread), and pretty much handed the boat back to me more broke than I dropped it off to him.

The drive I mentioned up in Michigan in that second thread was in amazing shape, and I picked it up for under $500 (easy stop while visiting family up there - basically God handed me a new drive for cheap). It was an easy out, so I grabbed it. I've kept all of my other parts. Cleaned up the original upper gear case last year, and it's sitting in reserve just in case. Right now I've got the other lower under the bench. I believe it's still a short, but since the wires were cut I'm not sure what to do with it yet. My intention is to fix it completely (I did energize the wires from a battery and it seems to be pulling the coils into gear), but that'll probably involve opening the lower gear case and I'm not quite confident in my doing that just yet.

So i checked this morning and I was getting 6 OHMS to both cables.

I was not able to check the boat side because of a dead battery which im charging now. When i test that i will let you know what i find.

And i tried putting 12v to only 1 wire at a time and i did not hear anything and was still able to spin the prop in both directions??? once i test the boat wires im going to try and mount the drive again and see if i have better results when its on the boat.

And Bruce yes it does have a grounding wire and was hooked up when i was testing it. I will make sure that where it is hooked up that it is bare metal and that its a good ground when i install the drive.

I will let you know tomorrow what i find out. (only have 1 hour each morning to work on the boat)

Thanks all for the replays.

When you measured 6 ohms, that was from one wire to the ground of the drive? Not measuring between the wires right?

6 ohms sounds right if its just one wire.

Correct... 1 wire at a time. Black lead to ground and red lead to either one of the wires.

Im hoping it was just not grounded properly when i had it on the boat and i will make sure the ground wire is connected to good bare metal when i install it again.
