Poly V marine serpentine belts are multi-V cross section belts with longitudinal v-shaped ribs, that mate perfectly with the corresponding pulley grooves. Poly V belts combine the high flexibility of Flat belts with the first-rate power transmission of V belts.
They are ideal for marine engine applications and enable economic solutions even under difficult drive conditions, such as large transmission ratios, high belt speed ratios, small pulley diameters and back idler pulleys.
