Need a reliable alternator for your Mercruiser 5.7L marine engine? This RareElectrical unit is a brand-new (not remanufactured) alternator that delivers 55 amps at 12V, with a 6-groove pulley. It replaces part numbers like AC155616, 807652T, 60055, 9-19102, and others. Designed for Mercruiser inboard engines from 1997–1998 (and other years), it’s built to handle the marine environment with corrosion-resistant components. Installation is straightforward if you’re familiar with engine electrical work. Always cross-reference your old alternator’s part number to ensure fit. Get your boat’s charging system back in action so you can spend less time at the dock and more time on the water.
