Twin propellers made in sturdy composite material (NIBRAL BTQ 300-300). Recommended boat length 20-26 m (65-85 ft). Solenoids protection carter in sturdy composite material. Composite material. Bronze gearbox. Independent zinc anode from the gearbox and easily replaceable. Equipped with elastic coupling.
The Gearbox is created so that the behaviour of the propeller is unaffected in either direction. The conical gears that make up the gearbox are reinforced and adjusted to ensure maximum efficiency.
No maintenance required as the highly resistent components guarantee a perfect seal against leakage of the lubricating oil.
The bronze propeller gear leg is provided with a hydrodynamic profile that minimises turbulence.
The Propellers guarantee maximum thrust performance and reduction in current absorption. Made of composite materials, resistant in every condition, and fastened with self-locking nuts in stainless steel.
The case that protects the reversing contactors is made of robust composite materials that are resistant to corrosion. The electrical connections are provided with quick connectors.
The elastic joint that optimises the alignment between motor and gearbox is an exclusive Quick design. This acts as an even tension device, preserving the operating system from impulses from the bow thruster, with above-average results.
The motors new-generation materials have been chosen to constantly guarantee required output and maximum performance, given the severe conditions required by the application. Protection against overheating of the motor is ensured by a microprocessor.
The support flange is completely in hard coat anodised aluminium.
