    1971 50hp hydroelectric drive throttle cable/ linkage adjustment

    Long story short, I was given a 1971 Glastron skiflite v142 with 50 hp Johnson hydroelectric drive. I have had a couple of issues with shifting and after working them out, I am now wondering about the throttle cable and linkage. I have the OMC manual that covers many models from 71' to 89' so it...

    1971 50 hp hydroelectric drive won't go into neutral

    I'm thinking it was an issue with plunger being out of adjustment then. I took the boat out and it shifted great. No problems with the shifting at all

    1971 50 hp hydroelectric drive won't go into neutral

    I'll be the first to say that this is weird and I knew it would be, I searched the entire internet and couldn't find someone with the same problem. I have been fixing things for a living for 22 years and I don't like when something is"fixed" and I don't know what fixed it..it had to be one of 3...

    1971 50 hp hydroelectric drive won't go into neutral

    I am in Dryden MI.. After cleaning up and reinstalling the solenoids I added oil to the lower unit and spinned the driveshaft with a drill while applying power to solenoid wires with jumper wires... forward, neutral, and reverse all worked fine. If not for a chunk of the o ring on the driveshaft...

    1971 50 hp hydroelectric drive won't go into neutral

    Also, the lower solenoid was slightly stuck when I went to remove it. When I cleaned everything up and reinstalled solenoids/shift rods, I noticed plunger wasn't flush with top of solenoid.. could these things cause this issue? I was going to add lube and retest it with plungers adjusted to see...

    Tubes are in this picture..so with oil drained, when I push down on neutral and reverse levers, they feel like they are already down as far as they can go, so I'm guessing that there isn't a spring under the ball valves to keep them unseated? Must just be the oil pressure that does this?

    1971 50 hp hydroelectric drive won't go into neutral

    In the exploded view of the lower unit it shows tubes going into the sides of the solenoids toward the top, I don't have the tubes and I don't see a spot where they would go.. the exploded view also shows a valve housing with neutral lever and balls and reverse lever and balls. The levers are...

    1971 50 hp hydroelectric drive won't go into neutral

    It stays in reverse..which is why I thought the blue and green wires could have been shorted together, but they aren't.. usually starts turning in forward for a split second and then bangs into reverse..I removed spark plugs so I wasn't starting engine each time I tried, so it's just the starter...

    1971 50 hp hydroelectric drive won't go into neutral

    I have the shift solenoids out now..I am having a hard time picturing how this setup works exactly..but I was wondering if there is anything that can be done to mimic the action of the solenoids using a piece of brazing rod or something as the shift rods to see if I have an issue with shift...

    Thanks for responding..I thought that could be a possibility so I submerged in water, that didn't work. Then the last thing I did was what you are saying..while cranking it by jumping the solenoid I used my foot to try to see if I could stop the prop but I couldn't

    1971 50 hp hydroelectric drive won't go into neutral

    Hi everyone, I'm sure nobody wants to see another thread on hydroelectric drive, and I'm sorry to say there is still at least 1 in existence..for now. I got mine as a gift about 5 years ago. It was given to me because I can usually fix things and it didn't work properly from day 1. When I got...
