Re: Stus-List Engine stalling after shifting
Dave, I had similar drama with my engine six years ago. It was made worse by a cantankerous starter. I once had to have guests steer while I jumped below and shorted the starter solenoid contacts with a big screw driver to start it. (docking was similar to Jack Lemon in The Wackiest Ship In The Army) I had the starter rebuilt. I was able to adjust my engine's idle speed by adjusting the throttle stop at the engine. I think it required two 9mm or 10mm wrenches. No problems since. When docking, I set the throttle and use the shifter to put it in and out of gear. I'm sure the idle is a little higher than spec, but now I feel less vibration and no stalling.

Re: Stus-List Engine stalling after shifting
I got a laser-tach from Amazon for ~$20. It came with reflective tape which you cut to size. I put a piece on the main pully and transmission output shaft. I used it to make sure of the accuracy of the installed tach and verify the gear ratio. Then I also used it to set the low idle speed. Low idle has to be tweeked for accuracy when cold and hot. Maybe it changes, maybe not. Various diesel additives are available but after searching the internet for comparisons based on lubricity the product that stood out was made by opti-lube. Their original formulation, XPD, seems to work well for me. The concentration is strong enough that you can actually smell the product after it has been properly mixed. By having the laser-tach I was actually able to detect about 200rpm increase in speed while at idle and a corresponding higher rpm while at full load.

Re: Stus-List Engine stalling after shifting
I had the same problem and did two things. 1. I made sure the fuel system was well bled A small amount of air trapped in the high pressure lines can create a lot of trouble with idle and stalling. 2. The second thing I did was add Howe's diesel fuel treatment to the fuel every time I fill up. The explanation I got was the fuel that was available when the M-430 was build had a high sulfur content which acted as a lubricant for the fuel injection system. The new (low sulfur) fuels don't provide the needed lubrication causing the governor to stick resulting in stalling. I'm not sure which (or both) fixed the problem, but I don't have the problem anymore. I hope this helps...
