15 HP tiller handle linkage slippage

[d.boat]

I have an early 80's ('83, I believe, I can find out if it's important) 15 HP Evinrude. There is a linkage on the tiller handle "joint" that regularly slips alignment of the linkage gear teeth. This is due to the fact that I have this motor on a trolling bracket on the back of my large boat and since it's lowered, the tiller handle has to be bent upward at that joint so I can operate it. All of this is within the normal operating range of that joint. But that position seems to be incompatable with the design, or the teeth are just worn from 27 years of use.

Other than not using it that way, anyone have any suggestion how to solve this problem or an easier way to re-align it? Right now, I just force the gear's teeth to re-align it.

This is really a fine little engine. Starts easily, runs smoothly, not a drop of leakage in the L/U, really clean little unit. I'd like to solve this irritating problem if possible.

Thanks.

hi.
in last weak i had almost the same problem.
my solution was to disasemble this grip which you hold in hand(take out one screw and unlock one lock washer), andd take out shaft with teath on the end.
after you"ll done this, take out second linkage teath element, using ziegier player to loosen ziegier locker washer.
take out this element, and there is round cats on the endas space for ziegier locker washer, i put round washer on it to push out that teath can join closer but to have enough space to put back linkage teath element i did wider groove for ziegier locker washer using a saw.

It is a problem for that series for sure. Loose isn't understating the problem. I think by 87 or 88 they replaced it with a cable drive throttle which must be a big improvement. Other than washers I don't know of a fix. Best of luck. Rick.

I'll probably take it apart and see if anything strikes me. Do you know if there is a way to actually replace it with a cable type arm from a later model (assuming I could find one in a bone yard somewhere)?

Thanks.

I dont think it would be possible, certainly not just a question of fitting a later type tiller.

Compare the diagrams for a 1983 with those for a 1986 model in the parts catalog.
