This Super High-Output alternator/generator is all you need to survive, covering all energy needs on your boat.

The frame is hard black anodized with a special salt water resistant coating that enhances heat dissipation, which is critical for any alternator over 160 amps. The bolt-on replacement, 250 amp GenMAAX gives you all the output of a large-case alternator in a small case that fits 99% of marine engines. Fits these Yanmar engines: 2GM 2GM20 2GM20-YUE 2GM20F 2GM20F-YUE 2GMF2YM15 3GM 3GM30 3GM30F 3GMF 3HM 3HM35 3HM35F 3HMF 3JH2 3JH2-TE 3JH3 3JH3-E 3JH4 3JH4-E 3JH5 3JH5-E 3YM20 3YM30 4JH 4JH-E 4JH-HTE 4JH-TE 4JH2 4JH2-DTE 4JH2-E 4JH2-HTE 4JH2-TE 4JH2-UTE 4JH3-E 4JH3-HTE 4JH3-TE 4JH4 4JH4-AE 4JH4-E 4JH4-HTE 4JH4-TE 4JH5 4JH5-E 4JH110 4JH80 4JH57 4LHA6LY 2QM15 2QM20 3QM30 3QM30(F) Specifically developed to meet the technical demands of the new generation AGM, Lithium and Gel Batteries, the GenMAAX 250 super-high-output alternator/generator produces a continuous 195 amps covering most cruisers’ daily energy needs in very short order.

Remote rectification has been in use for decades in industrial applications and removing the rectifier out of the rear of the alternator and placing it a few feet away, has many benefits. By far the single biggest benefit is that over 50% of the heat has been removed from the alternator. Only the heat generated by the stator remains.

In addition, the air space now available due to the removal of the rectifier which allows the twin fans attached to the rotor to work more efficiently by greatly enhancing heat dissipation too. With the remote being up to 48” away from the alternator and engine, the device can be located next to the batteries in a generally more cooler and dryer place. Now there are no connections needed at the back of the alternator.

This allows for the output of a large frame alternator in a small case alternator frame. Due to no wiring at the back of the alternator (now done at the face of the Remote Rectifier) makes the wiring hookup much simpler too.
