Stone Marine Propulsion NGC tunnel thrusters can be supplied with fixed pitch propellers (NFT) or controllable pitch propellers (NCT). They are designed to be simple and highly efficient with the fixed pitch version providing reliable performance for all types of vessels and ships. The CPP version allows the use of skewed blades which result in low levels of cavitation and vibration for applications where minimum noise is a main requirement.
The propellers are manufactured from high strength Ni-Al-BR and the drive shaft and gears from high quality alloy steel ensuring a long and reliable service life.
The systems are usually supplied as four separate units, the prime mover, the hydraulic system, the remote control and mechanical sections. Although the prime mover is usually an electric motor, diesel or hydraulic motors can also be supplied.
