I recommend checking-out www.yanmarhelp.com. The site was not all that
easy to find but once connected I had some very specific back and forth
discussion with their help desk guru which saved me a lot of time and
trouble figuring out an overheating problem with my 3GM30.

Good luck,
Scott

Good morning

I hope someone can help with an annoying problem.
I have a Yanmar 1GM10 inboard on my small sailing boat. It runs really
well. Recently I had it serviced, oil changed etc. including replacing the
impeller.
