I agree - so it is. However, in TrentePieds there isn't really a choice, and it doesn't worry me particularly since cable breaks are exceeding rare and the warning symptoms of an imminent cable break would be obvious. You would know of impending problems at start-up.
On my Vetus - which is a Mitsubishi tractor engine - the shut down is a "normally open" valve within the pump. Closing that valve will kill the engine at any RPM
including WOT. It is solenoid operated with manual override. The override is of necessity situated right on the pump body and therefore awkward to get at. I have wired the solenoid to a button in the cabin
so, if necessary, I can stand back from the engine casing and kill the engine without going on deck
as well as from the cockpit steering
position. But my reason for making that modification is that I have no faith in the pretty-pretty little toy buttons in the Vetus control panel
in the cockpit
. The cabin
mounted button is a grown-up Perko.
With the clamp on the cable "backed off" the control lever goes to idle. Sensible enuff of Mitsubishi to make idle the "default". I imagine that all engine manufacturers do that, but it'd be easy enuff to verify on any installation
