The New XT-Series Alternators from Balmar bring together the latest innovations in alternator design to deliver incredible charging power in a compact, Marine-friendly package.

Wakeboating on waterOver 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.

XT-170 and XT-250 Alternators produce over 120A and 180A, respectively at idle speed – ample power to service all electrical loads with power left over to top-off house batteries. The XT-Series pays for itself in reduced battery replacement costs in just one year!

Available XT-Series mounting styles are drop-in compatible for WakeBoat and other GM gasoline engine applications and include both 2“ Single Foot (Delco 11Si Style) and Vortec (Delco 9Si Style) designs.
