Older Evinrude 100 H.P electric shift problem

I recently purchased a older Boat with a 100 H.P. Evinrude Motor. It has the old style push button electric shift on it. I pushed the center button which is suppose to be for nuetral and its still in gear. I tried pushing the forward and the reverse button to see if either of them would change anything and it still is stuck in gear. I started the motor because I heard from a friend that the motor must be turning over in order for it to change gears but that it still didnt change anything. This motor was purchased from a older man who passed away and it seems as if he was very knowledgable and his motor seems to be very well kept so I dont think it would be anything major but I could be wrong! Is there a way to check and see if the shift box is working or if the electric shift is working right? Maybe someone knows a way to check these? Also I took off the controls to see if the wires were conected and there was a wire connected to the forward button, and the nuetral button but I didn't see a wire connected under the reverse button? Any ideas or self checks that I could perform would greatly help. Thank you.

What year/model is the 100?

And welcome to the forum.

Re: Older Evinrude 100 H.P electric shift problem

What year? Is it a hydro electric shift (1972)? Could be shift switch in remote control or your lower solenoids are gone. If the lower unit solenoids are gone it will default to forward. Power to the green wire gives you neutral, power to both green and blue gives you reverse. Run a wire to the connections at the lower unit and run a pig tail from the starter solenoid to those wires. But until we have a model year that's all I can say. Do a search and you should find your answer. Good luck... it's here some where.

It is a 1971 100 H.P evinrude. I found the model number which was 100193 which using the chart I found online means its a 1971 Evinrude 100 h.p. Hope this helps

Re: Older Evinrude 100 H.P electric shift problem

If that is the engine I think it is, it has the electro-matic shift. It works entirely different than the hydro-electric. On the right side of the engine, in the lower pan you will find two wires, blue, and green. These two wires will run into the exhaust housing. They both have a rubber sleeve. Slide each sleeve back and seperate what is called a knife connector. With a ohm meter, connect the black lead to ground, and the red lead to each wire one at a time. This should give a reading of 6 ohm's. If it does, this shows the electric coils are OK. Connect the two meter leads to the blue, and green wire. If you get a reading, this would show that the wires are shorted together inside the exhaust housing. Not all that unlikely on that age engine. Make these tests, and we can go from there.

Re: Older Evinrude 100 H.P electric shift problem

Ok, I got out my ohm's tester and you are correct, there are two wires on the right side that run down into the exhaust housing. I dis connected them at the knife connector and got a reading just slightly higher that 6 ohm's. I also performed the wire short test and when I connected the meter wires to the blue and the green there was no reading so i'm assuming I dont have a short. Hope this helps you help me!

Re: Older Evinrude 100 H.P electric shift problem

I just relized I put Regular 80/90w lower unit oil in it instead of
type C lower unit oil. I'm not sure if this would cause it to be sticking in forward or not but i will change it in the morning. Any other ideas will help!

Disregard my post. You have a hydro-electric drive. I got it in my head you were talking about the older electro-matic.

How does the hydro-electric shift work?

Re: Older Evinrude 100 H.P electric shift problem

How does the hydro-electric shift work?

There are tons of posts on this forum about that system. Briefly. the motor is shifted by hydraulic pressure produced by an oil pump in the lower unit. That is why it has to be running in order to shift. When not running, or in case of failure of any part of the system, it defaults to forward gear.

The flow of hydraulic oil and shifting is controlled by a pair of electrical solenoids, also in the lower unit. All the solenoids do is close a couple of flow control valves when energized.

The push button switch provides the electric voltage to the solenoids.

Any troubleshooting of the system should always start with making sure it is full of the correct oil, and not water. Then check the electrical system, especially the push button switch which is notorious fo being bad. Everybody wants to blame the solenoids, but they are low on the list of common problems.

The push button switch is getting hard to find and is extremely expensive.

Thanks to everyone who helped me with this problem. I found that the problem was I put the wrong gear lube in the lower unit. I changed the gear lube and put the premium blend for electric shift in it and it works great in all three gears. Thanks again, I appreciate the help.

Re: Older Evinrude 100 H.P electric shift problem

I know it's been awhile on this thread maybe I could get some help as well.

1970 60073b 60HP

Shifted just fine until I changed the water pump

Didn't know the correct steps after disconnected the wires and then removing the lower unit

I removed the solenoids instead.

I put everything back together. All I get is a click noise either going to R or N

But it's stuck in forward gear.

I took my time and thought I had it put together correctly

Where do I start ?

What could I have screwed up ?

Yes my apologies

It's difficult to see all the links while using my smart phone.
