Thruster propeller 3bl for 4hp for 12mm shaft. Ø185mm, up to year 1994.
TWIN PROPELLERS
Twin propellers can provide more thrust than a single propeller system in the same tunnel diameter. We use this system in our mid-range models, where high thrust is required in small tunnel diameters. Due to the compact design and high performance, the twin models have become the thrusters of choice among boatbuilders worldwide.
