Inc. SMI Thrusters feature a hydrodynamically streamlined Ni-resist gear case. The high nickel content of the gear case makes it durable and non-corrosive. SMI Thruster's design ratio of the hub to propeller and tunnel diameter provides maximum thrust efficiency. SMI incorporates the latest developments in gear transmission with properly matched modern propeller design to produce a line of thrusters which succeeded in converting engine power into maximum full-power operating capability.
Materials used in the manufacturing are premium alloys of the highest quality.
Gear Sets are hardened and lapped in pairs, larger gears are hardened and ground. Materials, tolerances, gear pattern and backlash are traceable through the SMI production record. The Application Engineering Department is immediately available to assist you in selecting the equipment which will efficiently and economically satisfy your individual design requirements. Product performance characteristics, certified dimensions, and installation recommendations are available upon request.
