Yanmar YSB12 -0 Turning Engine Off

New to this boat, sailing, etc.

The online manual says not to use the pullout engine stop to turn the engine off. Just pushing the speed control lever all of the way down on the Edson steering post doesn''t stop the engine. It just keeps running (slowly). Is there an adjustment for this?

Yanmar YSB12 -0 Turning Engine Off

I would talk to Yanmar about this. My Yanmar stops by pushing speed control all the way off. I hate and it is one of the things I am going to change before the season starts. With the throttle as shut off you have to be very careful when docking that you don''t turn of your engine. In a tight spot the last thing I want to have to do is take precious seconds to make sure I don''t kill my engine with the throttle.

You can adjust the cable (throttle), by making it longer with the nut that is on the cable. You can turn nut to lenghten or shorten movement of cable.

Take a look at the lever (throttle) on the Engine as it moves when you move the throttle in the cockpit. you may be able to lenghten cable at engine; if not you can lenghten cable in binnacle (for sure). But, it is difficult.
If you cannot fix it, this is really a question for a ''ENGINE CONTROLS" PERSON. OR, a mechanic could make a kill switch that shuts off the fuel to engine.

Re: Yanmar YSB12 -0 Turning Engine Off

The Book says do not use the decompression pull out to stop the engine. I am not sure exactly why. I know that previous owners of my YSB 12, have. I do not. I just throttle back and let it stop running. (turn the key off.). I have never had a problem stalling it, as I never turn it off until I am in my slip.I just put it in neutral, throttle back a little, and slide into my slip. If I need to move forward or back the engine is still running.

Re: Yanmar YSB12 -0 Turning Engine Off

On most Yanmar engines there are two ways to stop the engine from running:

1. Engine Stop control that is normally found on the engine control panel .... Pulling this control resets and lowers the idle speed to below that which will sustain the engine idle rpm ... and the engine stalls/stops. This is the normal way to stop any marine diesel engine - some call this the 'Idle Kick Down' control. This 'idle kick down' control is ultimately connected to the engine's governor and fuel injection pump control.

2. Decompression - it causes the engines combustion chamber valves to stay open thus compression/ignition of the fuel mixture is impossible. A good way to shut down when the 'Idle Down Kick" is inoperative or faulty. This isnt a normal way to shut down a marine diesel engine, its there as an emergency backup way to shut down if the 'idle kick down' fails to stop the engine, etc.

Re: Yanmar YSB12 -0 Turning Engine Off

I have owned 2 Yanmars, 1 Farymann, and 1 Volvo diesel. None had a kill switch, all were stopped by backing the throttle to the stop. To add one would require a solenoid and other modifications to an engine without one as far as I know.

I have always understood that the decompression lever is not to be used on a running diesel as it can damage the valves. The emergency method to stop a diesel is to restrict the air intake.

My YSB12 has a stop pull control on the panel. the cable was shot and I am in the process of replacing the cable. It connects to the engine throttle lever and will shut the engine when properly adjusted.

Re: Yanmar YSB12 -0 Turning Engine Off

my yanmar 2gm had a pull lever on the panel...that was what stopped the engine just like thunderbay says.

the manual specifically said to not use the key switch for this as it can will damage the feed wires to the alternator and or something else, cant remember, probably a solenoid somewhere

Re: Yanmar YSB12 -0 Turning Engine Off

When finished with the cable, I will take some photos and try to figure out how to post them. I am new to this board.
