Throttle with a mind of it's own
 

I’m finding the engine on my boat a bit like Microsoft software. It
"knows" what you want to do so it won’t let you do what you really
want to do. Whenever I set the RPM above 1800, it gradually slips back
unless I keep my hand on the lever.

I’ve looked around the Edson pedestal and can’t find anything that
looks like a cable friction adjustment. The owner’s association said
West Marine has a special clamp to go on the cable for these
situations but the local store never heard of such a thing.

The engine is a 1980 Yanmar 2QM20. Anybody got a good idea?

Mine does that too but being lazy, i just tied a rope around it and I
tie it down. Eventually, I put a prusik knot in the end of the rope
which i put around another rope tied to an eye so I can adjust the
tension. Maybe I'll really fix it some day.

Too much maintenance. Who lubricated the cable? Who lubricated and
cleaned the throttle control?! Too much maintenance....

You know you've had a rough night when you wake up and your outlined in
chalk.

It hasn't been touched in six years except for the boatyard's recent
adjustment of the travel so the engine would shut down.

Should I squirt some salt water into it?

Guy lubricated mine before I could stop him. I'd heard about this
happening. I got lucky or something because it still works nice and
doesn't slip.

I've heard that Yanmar makes a "special" friction device, just for
this. I have no specific personal knowledge of it; but I'll bet it's a
simple physical device and, therefore, is priced astronomically.

P.S. Back in the old days when I worked for MS, I used to sometimes see
a VW bug parked there with a vanity plate reading "FEATURE." Funny guy.

Perhaps the mechanic also re-led the cable more fairly. When we got ours
repowered, they looped most of the shut-off cable and tie-wrapped it.
REALLY increased drag. When I undid that, friction disappeared.

If you introduce a loop, or tighten one slightly, you might get just
enough friction.

Wonder if the cable center is worn down? These things seem to be built
with self-drag-from-lack-of-oil in mind.

Hee hee....I think it's too late for that...(c;

Vise Grips squeezing the throttle cable?....

I stayed out of this because I don't know the brand name of the device I
bought (from Go2Marine.com) but my Regal's throttle was driving me nuts.
It would start out at an ideal RPM and the first wave we bounced on
would throw the setting off. On a cruise off RI I had my hand on it
adjusting it all the time. Drove me nuts.

The device I ordered is designed to do what others have discussed. It is
an adjustable screw that clamps down on the cable so one can add as much
friction as necessary to lock the throttle setting in place. I was
warned it will shorten cable life, but not having experienced that yet,
I felt I had no choice but to take action.
