Balmar Alternator 1-2" Single Foot Dual V Pulley - 170A - 12V

The Balmar Alternator 1-2" Single Foot Dual V Pulley - 170A - 12V is purpose-built for serious anglers and boaters who demand reliable electrical charging across extended time on the water. Whether you're running extended trolling sessions, powering onboard electronics, or maintaining battery reserves during multi-day trips, this 170-amp alternator handles the demanding electrical loads modern marine vessels require. Balmar alternators are industry standards for marine applications because they deliver consistent output in the variable conditions unique to saltwater and freshwater environments.

This alternator features a dual V-pulley design with a single-foot mounting bracket, engineered to fit 1-2" shaft applications on most standard marine engines. The dual V-groove configuration optimizes belt grip and power transmission efficiency, reducing slippage during high-demand cycles—critical when fish finders, livewells, and navigation systems draw simultaneous current. The 170-amp output at 12-volts ensures rapid battery replenishment and stable voltage regulation even under heavy auxiliary load, minimizing the risk of system voltage drops that compromise electronics or upset fishing conditions during critical moments.

Boaters upgrading aging charging systems or installing new electronics will find this alternator compatible with most inboard and outboard applications using serpentine or V-belt drive systems. The single-foot bracket design simplifies mounting and aligns well with common engine configurations found on fishing boats and cruising vessels. At 14.8 pounds with compact dimensions of 10 x 9 x 10 inches, it installs without major structural modifications. For anglers running GPS, sonar arrays, cabin lighting, or refrigeration systems, the 170-amp capacity ensures your battery bank stays charged throughout the day, eliminating the downtime that costs fishing time and tournament opportunities.
