7 Series Alternators

Dual internally-fanned 70, 71, 712-Series alternators truly bridge the gap between gasoline and diesel marine engines by combining the high-output and superior low cut-in characteristics of our premium small case alternators with a sealed construction that meets international  ISO and SAE standards, as well as USCG standards for ignition protection. With an impressive top-end rotor speed of 12,000 r.p.m., this new alternator is an ideal choice for Mercruisers and other high-performance marine engines with cruising speeds meeting or exceeding 5000 r.p.m. Available in 1'' (71-Series), 2'' (712-Series) single-foot, and dual-foot (3.15"ID) saddle-style mounts. 2.5" x single deep vee pulley is standard.
