2GM20F Zinc Anodes
I have a Yanmar 18 HP 2GM20F diesel in my sailboat and was hoping for
someone with that engine or similar could answer my question about the zinc anode. I was wondering if this engine has one and where is it located. The manual states indirectly that there is one( i.e. it states the zinc anode should be replaced periodically). But the manual does not identify a location or a part number. Nor can I find it anywhere on the engine unless it's hidden under some piece. Has anyone else had this problem? Frank |

Frank Par 4.3.4 from the maintenance book Inspection and replace anti-corrosive zinc 1 Close the kingston cock 2 drain the cooling seawater 3 remove the plug labeled ZINC 4 check the plug on the inside of the plug to determinate the amount of wear top the anti-corrosive zinc. ( replace the anti-corrosive zinc when it has been reduced to less than 1/2 of its original size) ( if there is only a little bit of wear, clean the surface by sanding off only corroded areas 5 replace plug 6 open the kingston cock and check water leakage. Inspection ** every 500 hours On I don't know at what point of the motor the zinc plug is located but a phone call to a dealer will help. Good luck, Ben |

Frank My Yanmar manual is pretty poor. It specifies a zinc for my 3gm30f (it's the same manual as for your 2gm20f) but there is no such animal. The zinc is for the raw water cooled (3gm30) model only. Very likely it's the same situation for the 2gm20f. The manual also specfies different gearbox lubes in dfferent places. I highly recommend purchasing the servce manual, which is much better and very useful if you are doing anything more complicated than an oil change. __________________________________________________ __________ Glen "Wiley" Wilson usenet1 SPAMNIX at worldwidewiley dot com To reply, lose the capitals and do the obvious.

The "F" stands for fresh water cooled.In this moter you do not have a zinc.If I
remember there is one in the heat exchanger though.I will look in the book later and let you know.Also do not mistake the engine zinc for the shat zinc.Either motor will have a shaft zinc. Benny |
