The Yanmar GM Series marine engine now has a specific Electromaax Serpentine Pulley Upgrade Kit that is extremely easy to install.  Now you can eliminate belt dust and/or upgrade to an Electromaax high out put marine alternator or both.

 

This kit now includes a second alternator pulley customized to your SPECIFIC original  (Hitachi) alternator.  This now makes the old Hitachi a spare or if you want it can remain as the primary.

 

Also NOW included a custom belt tension arm that ensures the alternator never moves.

 

In addition it makes the installation a breeze.  The new 10 groove serpentine (micro ‘V’) crank pulley simply slips over your current crankshaft pulley and is secured with the bolts supplied.
