Yanmar YSE8

The Tanzer 26 I was on yesterday had the standard two levers, one for transmission and one for throttle. It did not have a shutoff lever however. The owner just shut it off by pulling the throttle back just a little past idle. There was no way to know you were at idle however. No extra resistance. It was really easy to shut down the engine by mistake or shift at too high a speed.

Is their something missing that makes this engine easier to use. Seems like a particularly evil design.

The YSE8 in my CS27 is the same and the Volvo MD1 I had in a Westerly 25 years ago was the same. As a matter of fact I have never owned a diesel with a stop cable. Other diesels I have owned were a Faryman and another Yanmar.
At least it's better than the 6-71 in the commercial troller I worked on. After running the engine I had to call the owner to find out how to shut it down. Turns out there was a lever - down below on the engine itself!

I have same two lever design on my yanmar 2qm15. There is an idle control stopper, located on the engine, where the cable coming to. Cable should be adjusted in such way that it wont shut down the engine until pulled all way down. I mean that there is some sort of lug, some distance in lever's travel between idle speed and shut down position. Also cable tensioners are available at marine/auto stores. It is very simple device -sort of clamp with tension bolt. It goes around a cable in any place you like and it just makes travel of the cable inside of its jacket more difficult and, as result, it gives more resistance on controls.

Overall I have no problem what so ever with two levers, as soon as got used to it.

In a properly setup system with the lug for example does this mean that once the throttle is at idle it takes an extra much harder push to get to the shutoff position. In my case there is no extra resistance.

The cable tensioner seems like a good idea in general so the throttle does not rattle itself to to another position. I had a Catalina 30 that I had to hold the throttle all the time. But what I'm looking for is some way to put the engine to idle reliably without accidentally moving the lever a quarter inch too far and shutting the engine off.
It strikes me as an obvious safety issue.
