This is a Universal M4-30. When I bought the boat, I had starting issues and cleaned all the grounds and have since replaced the wiring harnesses. It has been 8 years, but the reason I was skeptical of a ground issue is that the engine has started every time on the first try when first warming the glow plugs. And it has started on the second try both times when not using the glow plugs. Does it make sense that a bad ground would work that way? Dave
