TM - Torque Master Gearcase

The 2.5 liter Torque Master gearcase, designed for boats with heavier loads and speeds to 85 MPH , features a built-in torque tab on the skeg for reduced steering torque.  Strut-mounted water pickups have stainless steel covers that direct water into the inlets, allowing outboards to be at elevated transom heights of 25" to 27" (635 mm to 685 mm), resulting in reduced drag and performance.

Three-liter Torque Master's feature dual water pickups (mounted on the nose of the torpedo and strut) for improved cooling while reducing ingestion of weeds.

Heavy duty 18 spline stainless steel propshaft and a painted housing for improved corrosinresistance.
















FM - Fleet Master Gearcase

The Fleet Master gearcase, similar in design to the Torque Master, features a painted housing for offshore applications.

Fleet Master gear housings feature dual water pickups (mounted on the nose of the torpedo and the strut) for additional water flow and cooling while reducing injestion of weeds. 

Internal components are designed for submerged operation and are built to withstand the corrosive saltwater environment. 

Internal updates include a new 19-spline stainless steel propshaft for enhanced corrosion resistance, a heavy-duty offshore bearing carrier and a double shot- peened pinion gear.

Painted housing for offshore applications.
