Red Arrow is shut off

Yellow Arrow is idle stop screw

On the side by the Light Blue Arrow is where you would find a solenoid if there is one.

Personally, this would be the ONLY solution for me. I cannot imagine it would be too difficult to engineer.

I think my plan will be to drill a small hole in both my morse controls and keep a peg on a small chain that I can use to limit throttle arm movement, but easily remove to shut off the engine.
Based on the photo all you have to do is adjust the throttle stop to keep the idle from dropping to low.

Check out the knob control push/pull cables on this page. You could rig a stop cable for $30.

Thanks for all the good advice.

I am hesitant to install only a single stop cable since I have a flybridge helm as well. I would want to be able to quickly turn off the engine in an emergency such as oil pressure drop, right?

To give you an added incentive, you may have both liability and insurance problems with the current setup if God forbid anything should happen. Unless you can establish that this was original and met the standards of the time I would think you might have problems claiming insurance coverage in an accident.

Frequently I stand a bit sideways facing to stbd. I reach accross w my right arm and do the shifting .. I think my shift and throttle are not on the usual sides. I usually make stbd landings. Then w my thumb and forefinger I run the throttle. This way I'm not switching hands and I can see well aft but fwd too. I have a throttle stop at 600rpm cold and 900 warm. When I'm backing I don't use the rudder unless I need to swing the stern w fwd gear. When needed or wanted I use up to 3/4 throttle in both gears .. more so in reverse.

Lots of time for making observations if there's no wind or current so 1000rpm is fine. But often quick maneurvers are necessary to move the boat (or one end of it) out of danger or worse. My $0.02

I think the root of the problem is simply that at some time the stop cable broke and someone jury-rigged it by setting the low idle to zero, then never fixed the stop cable. Replace the stop cable with one or two cables and readjust the idle stop and you are back to a correct and functional setup.

I also usually make starboard landings. I'm able to reach the wheel as well as engine and thruster controls with the left hand when standing on the starboard deck for best visibility. Since the boat has starboard propwalk, applying power helps snuggle the boat to the dock when landing. When leaving, the bow thruster can angle the stern to port to counter the propwalk.

Don't mickey mouse a mickey mouse.

Readjust the low speed stop properly so the engine no longer stalls. That is not correct and as pointed out may be dangerous/disastrous.

Then properly repair the shutdown with either an electric solenoid as the engine was designed to have or rig a manual cable, two which could be tandemed or paralleled, to do the shutdown properly and safely.

Tandem meaning one cable from bridge connects to the lower helm cable so only one cable goes to the shutdown lever on the pump from the join at the lower helm.

Parallel meaning two cables go directly to the the shutdown lever on the pump.

Years ago our purchased new sailboat came with a Morse dual lever system that was designed such that pulling all the way back on the throttle would shut down the engine. So they did manufacture them that way, although I don't think it was the brightest design feature.

Hey... you guys check my work, but I think this is all you need to do. All of these parts can be just off-the-shelf auto store or West Marine parts. You might have to source a used solenoid or get one from a local commercial truck parts store.

You really do not NEED to be able to shut down from your upper station.
So a cable or switch from below will be fine.

Until it sticks in gear and you're heading straight for some one else's boat.

I dont see any mechanical connection between the throttle and the shutoff levers.

Exactly. That is the problem. The fuel control is allowed to go below low idle until the engine starves and "stalls".

The OP should consider a simple pull cable to manually shut off the engine. This would allow him to use the control to adjust engine RPM. Most controls are set up so that full back on the fuel takes you to low idle. His shuts down the engine.

Single lever controls use the same cables as the double.

I would heartily agree with the elimination of the ability to use low throttle as shutdown issue. That is simply out of adjustment.

Have you looked at the governor for the shutdown lever? I would bet dollars to donuts that there IS a lever there ( all diesels have some type of compression release or fuel rack lever) and it probably has (had) a separate shutdown pull, push, or electric solenoid to shut it down.

Thinking back to the 40 to 50 diesel boats I have run over the course of my career I do not recall one that has ever had the primary or even possible way to shut down the engine via the throttle lever. The most common way without using an electric solenoid is to use a semi rigid push/pull cable to shut it down and then push it back in so it will run next time. Not every station needs the shutdown ability. Just the main one, which is in fairly close proximity to the start button. If you go with cable, you need to look for 'panel mount cable'. With a 'T' handle.

Believe it or not, the Yanmar 2QM20 actually featured a "Stop" position on the throttle quadrant. It required pulling the throttle lever back beyond the "Idle" detent position into the "Stop" position to stop the engine. This was not a single lever combination control, there was a separate gear selector control. It was very problematic and was discontinued on their later auxiliary diesels. The injection pump had no stop lever or stop solenoid. The only way to stop the engine was using the "Stop" position on the throttle. Here is the detail from the owners manual. It was a mess and hard to keep adjusted.

In looking at the pic of the injection pump provided by the OP, there definitely appears to be a stop lever visible. Not like this weird Yanmar stop arrangement.

Fine for the lawnmower, not fine for the boat.
