Balmar XTDF170K63YM XT Series Alternator, 3.15" with a K6 Pulley (fit Yanmar)

For WakeBoat and Inboard Gas Applications. State-of-the-art, braided wire stator design to generate exceptional output in the smallest possible area. An industry-best 85% copper windings density provides more power at low RPM, higher overall power and cooler operation. Compatible for WakeBoat and other GM gasoline engines. Over 60% of WakeBoat run times are at idle speed. Many high current electrical loads are engaged at idle, including ballast pumps, high-output stereo systems and multiple instrumentation loads. Dealers report that AGM batteries which should last 5-7 years on these vessels are being replaced annually. The XT-Series Alternator produces over 100A at idle speed – ample power to service all electrical loads with power left over to top-off house batteries.
