Yanmar 3JH4E Cold Weather Starting

The Yanmar 3JH4E does not have glow plugs, but Yanmar instead offers an optional intake Air Heater to help with cold weather starting.

The engine on our 387 does not have this optional heater, but I believe the blue “glow plug” wire from the start switch is run all the way through/to the engine wiring harness (the 3-conductor plug on the Yanmar harness), and from there on to the stbd side of the engine block itself.  Meaning, I think, that all of the wiring is in place so you could just drop in the optional intake Air Heater and plug it in if you were inclined to.
