Re: Yanmar 3YM30AE with SD25 raw water flow issue

50 engine hours later, I'm happy to report that everything looks good. No white smoke anymore, the water flowing out of the exhaust is same quantity both engines. The culprit was that undocumented raw water inlet that was plugged by growth. Now I have a long 70mm rod at hand to clean the inlet at regular intervals.
