Balmar SF170IR Xt-Series Alternator, 170 Amp

For WakeBoat and Inboard Gas Applications.State-of-the-art, braided wire stator design to generate exceptional output in the smallest possible area. The XT-Series stator achieves an industry-best 85% copper windings density which provides more power at low RPM, higher overall power and cooler operation. Mounting styles are drop-in compatible for WakeBoat and other GM gasoline engine applications. 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. Standard alternators only produce about 30A-40A at idle speed, leaving these loads to be serviced by onboard batteries. Excessive draining causes battery sulfation and reduced lifetimes. 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.
