PRM 90 D2.5 2.5:1 Marine Gearbox

PRM 90 D2.5 Gearbox

The PRM 90 D2.5 is designed for the rigorous demands of small sailboats and inland craft, acting as the definitive mechanical solution for a reliable physical bridge to torque safety. As a premier PRM marine gearbox, this unit utilizes a 2.5:1 reduction to deliver superior hydrodynamic power for low-horsepower diesel engines. The hardware architecture focuses on mechanical simplicity, ensuring this PRM power system maintains gear integrity through a robust offset-shaft design that facilitates easy installation in narrow bilge areas.

Technology-driven mechanical performance provides total protection through a reliable cone-clutch engagement system that requires no complex hydraulics. This PRM marine transmission features a high-grade cast iron housing to mitigate vibration and provide excellent structural durability in harsh maritime environments. Reliability is reinforced by the precision-hobbed gears and robust output flange designed for consistent light-duty service. This unit is the ideal choice for mariners prioritizing professional maritime power and mechanical drivetrain simplicity.
