Re: Yanmar hard starting question
Building a diesel without glow plugs is cheaper than building it with them. And since recreational boaters are cheap and tend to not use their boats in cold weather...It sadly makes good sense to build cheap engines without glow plugs.
It also would make sense to check the options for the engine oil. Most old manuals will spec a single-viscosity oil because motor oils weren't very talented 30 years ago. These days? Odds are you can use a good synthetic, and those are available in multi-viscosity ranges like 0W40 or 0w30 which make cold starts real easy. Much kinder to the engine.
