New Bedford’s Imtra has rolled out distribution of a new line called Side-Power thrusters, available in four different tunnel sizes to fit a range of commercial applications for retrofits or new builds. The new thrusters have 12-, 16-, 20- or 24-inch tunnels, with all sizes packing 3,000 pounds of force thrust. Each unit has two heavy-duty bronze, five-blade propellers that counter-rotate, exerting thrust in two directions and offering more control than single propeller thrusters.

They have an oil-fed gear lubrication system, and the oil can be changed for the two larger sizes, while the boat is in the water to avoid expensive haulouts. Gearlegs on the Side-Power thrusters have been designed to be as compact and low profile as possible, maximizing water flow through the propellers and increasing the thrust output.

“The Side-Power range of thrusters are reliable, powerful, and ideal for the kinds of demanding conditions commercial vessels encounter every day. We are confident this new range of products will be an important addition to your retrofit or newbuild,” said Alex Larson, Imtra’s vice president of commercial sales.
