ElectroMaax alternator surpetine pulley kits

The perfect solution to limitied space engine rooms and the JH3

If the engine room space won't allow the mounting of a second alternator kit consider an ElectroMaax surpetine belt kit. Use the space of the original Yanmar alternator and a new ElectroMaax highoutput alternator to increace charge amps up to 190 battery boosting amps.

Simple as bolting on 190 amps

Simple as removing the original alternator and bolting in an ElectroMaax 120-180 amp high output marine alternator and our new pulley kit. The custom 10 groove drive pulleys allow the use of a high output marine alternator providing all power needed on most smaller cruising yachts.
