Buyers Guide

Note that not all identical motors use the same anodes. This is because installers specify the motor “trim” which includes coolers. The following are guidelines for part numbers and engine kits, but there may be some variability in both size and number of zincs required. When in doubt, the defining characteristics are NPT plug size, zinc diameter and length (measured from end of zinc to where zinc meets plug). This Guide is “under construction”. More information will be added over time. If you have questions or need help identifying a part number please contact us. Likewise, if you have information that we can add to this guide, your input to the community is appreciated.

Note Yanmar parts may have different wrench size, but all functional dimensions are identical.
