Serpentine Pulley Kits For Yanmar Engines

Home > Products > Serpentine Pulley Upgrade Kits > Yanmar Engines

Finally a simple solution for those cruisers with Yanmar engines that only need to solve their belt dust problem. So, if you have any Yanmar engine with the Hitachi 55, 60 or 80 amp alternators, we now have a kit for those alternators.

GM series Yanmar enginesThe beauty of the system is that it includes the current serpentine pulleys for the water pump and crank.

There is no need to remove the Hitachi or the fan on the front as the new custom Hitachi serpentine pulley can be installed retro fit, while the alternator is on the engine.

This also means no additional wiring is needed and it reduces installation time substantially. This means that if in the future you do decide to upgrade to an Electromaax, or any other high output alternator, you will only require one new pulley for the alternator itself.

Is there a difference between Electromaax and Altmount marine alternators?

There sure is! Check out our comparison chart here.

The big benefit for you when upgrading your kits is that you will have two alternator pulley’s enabling the Hitachi to remain as a simple bolt on the replacement back up alternator. This saves you time and money, and the head ache of trying to switch alternator pulleys while under way.
