Before you go do all that work and expense test the glow plugs. Use a digital laser thermometer and with a cold engine activate the glow plugs. Maybe even do it twice. Aim the laser thermometer at each glow plug. If you see any temp rise that glow plug is working. Glow plugs are 100% or 0% working. there is no inbetween.

I have never thought about replacing the glow plugs which I can only assume are original to the boat/engine (27 year old Universal M4-30). I haven’t looked yet, but from the manual they appear to be on the starboard side and the engine is only accessible from the front and port side. Has anyone done this job? I am guessing it is pretty trivial if you have top access and pretty challenging if you don’t. Is this something that one can expect should need replacing on a 27 year old engine?
