Need Pics Early 60's 75hp

[yorab]

I could use a few pics of a 1963, or thereabouts, 75hp. Specifically, I need to see how to route the reverse lock cable. They way I have it now doesn't seem quite right because the cable rubs on the bolt, #29 in the diagram. I also need to figure out how the cable collar, #60 in the diagram, and the collar spring, #79 attach to the swivel bracket. Thanks.

Re: Need Pics Early 60's 75hp

I looked at the parts manual for the 1963 75hp Johnson. It's basically the same as my motor (Evinrude) but there are a few minor differences. In the exploded parts diagram, I can see that the tag end of the cable is loose, just as mine was. That cable collar and spring that I mentioned must attach to the 'main' cable somewhere but I still can't figure out where. At first I thought that the small collar spring keeps tension on the reverse lock lever, but I realized that the two bigger springs (#28 in this diagram) do that job. I still can't figure this out. I've attached a few pics of my bracket during disassembly. I can use advice if anybody has some for this topic.

By the way, the cable is #30, the collar spring is #32 and the collar is #75 in this Johnson parts diagram.

My 1962 Johnson 75 is long-gone but I do have a 1968 Johnson 100 which I believe has all the same parts/pieces. Will try to get you pictures this weekend when my son can help me tilt the motor because it is currently mounted to a work stand.

Re: Need Pics Early 60's 75hp

Okay, thanks Willyclay. In summary, I need to know 2 things: 1) does your cable rub on the long thru-bolt (equivalent to #29 in my original diagram) very close to where it attaches to the reverse lock lever?

And 2) where the heck does that collar and spring attach to the cable and to the bracket?

Thanks again.

Re: Need Pics Early 60's 75hp

I remembered working on this with my 75 and found some remains in my parts bin. Don't know if any of these views help you understand how to rig things but thought I would post them. Hopefully, you can see how the cable is routed over the transom clamp on my 100HP motor. It goes into a ferrule/tube and does not rub on the bolt but the 100 transom clamp appears to have been re-engineered to handle more power. Still need help to take a picture while I have it tilted and see what's underneath. Will keep trying. I did not find a "collar and/or collar spring" in my parts. Good luck!

Re: Need Pics Early 60's 75hp

Willyclay, I can see from your 3rd pic that the cable is routed above that thru bolt and goes from the lock lever into the ferrule/tube. I don't have that ferrule/tube on my swivel bracket. This must be part #80, "cable bushing", in my original post. I'll need to get it. That will keep my cable 'up' above the thru bolt.

I see from the parts diagram of your motor that you should also have the cable collar and cable collar spring, but for the life of me, I can't see a reason for them. If I could figure out why they are needed, it would be easy to figure out where need to be attached.

Re: Need Pics Early 60's 75hp

It's kinda funny that some of the early '60s models show that cable bushing and some don't, even when they use the exact same swivel bracket. I've just checked a bunch of different models and it seems random whether they have that bushing. For instance, my '63 Starflite model shows the bushing as can be seen in the diagram in the first post. However, the '63 Seahorse model does not show the bushing as can be seen in the diagram in my second post. But both have the same swivel bracket part number. Perhaps it isn't such a big deal for the cable to rub on the thru bolt.

Agree totally! Obviously the bushing exists on my 1968 motor also. The cable collar question may be as simple as OMC redesigned the cable with an integral ball/tip as opposed to needing separate parts (collar & screw) to secure it to the lock/release handle OR vice versa. The cable from my 75 and the existing one on my 100 both look identical to me with the ball/tip. All I know is that it works. The "collar spring" thingy is still a mystery to me. I will try to get under my motor today with an inspection mirror and see what I can find. Hang in there, you can whip it!

Re: Need Pics Early 60's 75hp

I got under my motor today and took some pictures but they are too dark to see any details even with flash. Sorry! Will try again tomorrow when it is sunny and 65F. Also, the "collar spring" may only be used on installations utilizing the "collar". Not much help but don't know what else to tell you. Good luck!

Re: Need Pics Early 60's 75hp

Okay, thanks Willyclay. Don't worry abuot the pics then. You've already helped my by showing that the cable goes over the thru bolt. If you don't have that collar and spring, then I won't need pics. If you do have them, then just describe it to me using the parts diagram. I should be able to understand where they go by your description.

Re: Need Pics Early 60's 75hp

Success! Both on your degree work and me finding the mysterious cable collar and collar spring. On my motor, the cable threads through the collar AFTER the cable passes through the bushing. The collar screw(75) appears to lock the collar and spring on the cable. The collar on my motor is positioned about halfway between the reverse lockout lever(29,34,35) on the bottom and where the cable emerges from the bushing on the top. The spring on my motor is NOT attached to anything on the bottom and it is not clear where it should go or what the function of the collar spring may be. FYI, it is a very light-weight spring that is only a fraction of th size of the tension springs(28) for the lockout mechanism. Also, it is worthy to note that my reverse lock mechanism does work without the collar spring being attached on one end. Sorry, but you may need a real expert like Joe Reeves or F_R to answer these questions. Good luck!

Re: Need Pics Early 60's 75hp

Okay, thanks again Willyclay. Now at least I know where that collar mounts. Perhaps it is meant to pull the cable to the side in order to route it around some obstruction? Just like your motor, my reverse lockout mechanism works without that collar. Maybe somebody will know what it does. If not, I'll just leave it off. However, I hate to just leave out a part without at least knowing what its function is. Especially since it will be a total pain to do anything with that collar once the mid section is mounted on to the boat. At this point, I have easy access to that area since the mid section is on my bench.

I'll be posting a bunch of pics of my motor rebuild under my rebuild thread sometime soon.

Re: Need Pics Early 60's 75hp

So, Willyclay, the only thing that I can think of is that the spring and collar help to take up any slack that may develop over time as the braided cable stretches. If there were no provision for taking up slack, then eventually the lockout mechanism wouldn't work unless one gets into that tight space around the swivel bracket and readjusts the cable tension. The collar and spring would make it so that the cable tension would not need to be adusted as often. That's my story and I'm stickin' to it

 

[Willyclay]

Re: Need Pics Early 60's 75hp

You are probably correct since the only possible location to secure the lower end of the collar spring is with the cable/rod connector screw, number 51 in your motor's parts diagram above. Would sure like to hear what one of the forum gurus has to say about this!

 

[yorab]

Re: Need Pics Early 60's 75hp

It's clear that the collar attaches to the cable at about the halfway point between the bushing and the cable connecting screw. It's also clear that one end of the spring attaches to the collar. I still can't figure out where to attach the other end of the spring. The other end of the spring must attach to the swivel bracket itself and not to a nearby part as mentioned in its name: "Spring - Collar to swivel bracket". I also realized that the spring is the same part number as the cam follower to manifold spring so it is indeed very lightweight. I've attached some pics. Maybe these will jog somebody's memory.

Re: Need Pics Early 60's 75hp

So, willyclay, I finally found a pic of that collar and spring on ebay. My swivel bracket is the same as the ebay photo and it's easy to see where the lower end of that spring attaches to the bracket. I'm still guessing that the purpose of the collar/spring is to take up slack as the cable stretches with repeated use. Thanks for your help with this.

 

[Willyclay]

Re: Need Pics Early 60's 75hp

Good detective work! I don't think that spring is strong enough to take up any slack but it might function as an anti-rattle device. I will look at mine again tomorrow. When are you going to splash that beauty?

 

[yorab]

Re: Need Pics Early 60's 75hp

The anti-rattle idea is a good one. That could be its purpose. I'll be getting this thing wet later this month or the beginning of April. But first, I need to wait until the weather warms up a bit here in central PA so that I can finish painting in my buddy's shed.

Re: Need Pics Early 60's 75hp

I looked at mine again but still cannot figure out where the lower connection point should be for the collar spring. Sorry!
