Here is a testimonial from an Electromaax customer who installed one of our marine alternators on his Yanmar 4JH4.
Here are some of the photos I took when installing the new Electromaax 180a alternator onto my Yanmar 4JH4E engine. A process that I’d describe as “easy peasy”, plus it works like a champ.
