*** REVERSE ROTATION ROTOR APPLICATION ***

This alternator uses a reverse rotation rotor and should only be used in applications where the engine is or will be operating in a counterclockwise direction. These applications are mostly found in twin-engine marine applications where one engine is standard rotation, and the other is reverse. Please note this alternator is identical to the standard M7127170 part number but uses the correct internal fans to properly evacuate the heat generated by the alternator. While running an alternator backwards will work, you end up losing appx. 20 to 30% of the cooling efficiency of how the alternator is intended to be used. High heat retention equals lower output and less longevity of the alternator.

*** FOR HIGHER AMPERAGE OUTPUT (240), PLEASE CONTACT US. MUST USE SERPENTINE PULLEY ***

This MechMan Marine certified high output 170 amp 6 phase alternator is a great upgrade for boats using the popular 6.61 inch center-to-center bolt pattern alternator. This style alternator was used by many boat manufacturers from the late 1960's through 2018. (check the technical drawing against the measurements of your stock alternator to see if this unit will fit your application) This alternator comes with a simple single wire pigtail plug included. 

Simply connect an ignition switched 12V+wire from the original alternator plug to the supplied alternator plug for proper function. This unit features (12) diodes and twin rectifier plates for excellent durability with high-end audio installations. This unit meets or exceeds SAEJ1171, ISO 8846, and USCG Title 33 standards for ignition protection.
