@arf145 : Yes , typically in summer we can get the engine started with full throttle and cranking for about 5 secs or less, and then throttle back to idle quickly. However as the temps have cooled even with full throttle its taking longer and longer to start. Hence the HEET spray question. Before this Yanmar 3GM30F I had a Westerbeke 20B with glow plugs, and that thing started fine after 10 secs of glow plug button no matter what the ambient temps. Unfortunately it seems the Yanmar has no glow plugs.
