Re: Pencil Zinc location for Yanmar 2GM
a 2GM raw water cooled motor, will have zincs in engine.
My 3GM raw water cooled motor has 2 zincs on starboard (fuel
filter/dip stick) side and 1 in back.
The 2GM raw water should have 2 zincs, 1 in the block on the dip stick side, just behind/above it . A second is on the rear side of the head. Check manual, should be available free on line.
...(1 could be hiding behind fuel filter like my 3GM)
