Where the engine and axles are separated from each other, as on four-wheel-drive and rear-wheel-drive vehicles, it is the propeller shaft that serves to transmit the drive force generated by the engine to the axles. The longer the shaft, the more liable it is to bend, and bending is further promoted when rotation is applied causing vibrations and resulting in an increase in noise. For this reason, the propeller shaft has been designed to suppress vibrations arising from a wide range of causes.

One end of a VETUS propeller shaft is, as standard, provided with a taper, a keyway with dimensions according to ISO 4566 plus matching key, a washer and a propeller nut with integrated zinc anode. The other end may be cut to length.

Material of VETUS Propeller Shafts
All VETUS propeller shafts are made of stainless steel type REMANIT 4462.
As far as corrosion resistance is concerned, REMANIT 4462 is equivalent to stainless steel of type AISI 316. However, REMANIT 4462 has a tensile strength which is approximately 30% greater and a hardness which is about 40% higher than that of AISI 316. It is the high degree of hardness that gives REMANIT 4462 its excellent running properties in bearings. All shafts supplied with key, washer and propeller nut with integrated zinc anode.

The key prevents relative rotation between the two parts and may enable torque transmission. For a key to function, the shaft and rotating machine element must have a keyway and a key seat, which is a slot and pocket in which the key fits.

Antifouling, Trilux 33 for Propeller
Due to their material, propellers and Z-drives require a special type of antifouling, which must be able to withstand high rotational speeds and abrasion caused by heavy water flow.

Peller-Clean Coat Transparent
An environmentally friendly, foul release coating to keep propellers, stern gear and outboards free from fouling. This foul release product uses silicon to provide a ultra-slippery surface that fouling finds difficult to adhere to. The box set comes with primer, finish, manual, gloves and brushes.
