Our Briggs Mini Drive is the latest addition to our airboat product list. This airboat unit is designed for the 35 HP Brigg and Stratton horizontal shaft engines. The unit is a plate style system using the eccentric center shaft to tighten the 50 mm wide drive belt, very similar to our other product lines. The output pulley also doubles as the propeller hub. This drive unit uses a standard metric bolt pattern and 8 mm cap screws to attach the propeller of your choice.
