Marine 2" foot 170 amp S series alt w/ V belt and 6 rib pulley
MechMan 6 phase hairpin marine alternators feature 12 diodes, twin pure copper rectifier plates and outstanding airflow to ensure long service life, even in the hot engine compartment conditions encountered in marine applications. MechMan marine alternators are made in the U.S.A., and feature coated rectifiers and housings to reduce corrosion. Featuring sealed brush-holders, these powerfull alternators meet SAE J1171, ISO 8846, and USCG Title 33 standards for ignition protection. Simply measure your original alternator and compare to the technical drawing to verify fitment. NOTE- as marine alternator pulley diameters vary, it may be necessary to install a slightly longer or shorter drive belt for proper belt tension. (available at your local autoparts store) MechMan marine alternators include the pigtail to plug into the alternator, which only requires an ignition switched 12V+ source to function normally. On most marine engines with OEM pulleys, this unit will make an impressive 120+ amps at engine idle RPM, with 170+ amps at cruising speed.
