Can anyone tell me the size of the plugs that hold the zincs on the Yanmar 3GM30
? I tried a 22 mm wrench but it's too small and I want to make sure the next time I go to my boat
, which is currently 8 hours away, I have the right socket. For my raw water
cooled engine there appears to be three zincs anodes - two on the right side of the engine (left side as you're facing the water pump), and one on the back.
I've never done this before but I'm interested in the comment from grahamb that the zincs are easy to check. It looks like one of them requires removing the fuel filter
housing, which then requires bleeding the system. Maybe you guys consider that easy, but I don't consider it particularly easy and it's messy. Am I missing something?
Thanks for your help,
