All Vetus propeller shafts are made of Duplex 1-4462.
As far as corrosion resistance is concerned, Duplex 1-4462 is equivalent to stainless steel, type AISI 316. However, it has a tensile strength which is about 30% higher and a hardness of about 40% higher then AISI 316. It is exactly this high degree of hardness which gives Duplex 1-4462 its excellent running properties in bearings. Moreover, it offers much more resistance against wear and tear in the way of bearings and seals. (Please note that older Vetus shafts were fabricated from Remanit 4418 which had different comparisons with AISI 316)
Shaft assemblies with dual shaft seal (25/30mm)
For use with less powerful engines, Vetus have designed and developed a shaft assembly - with shaft diameters of 25 mm or 30mm - which can be installed with a minimum of fuss. Machining, threading and keyway cutting have all been taken care of. In addition, these shaft assemblies protect the environment: lubrication is ensured by means of raw water, without use of grease or oil. The stern tube is provided with a dual shaft seal, eliminating the need for a stuffing box. The stern tube may be supplied in either bronze or GRP.

Propellers
A ship's propeller is possibly the most important component of a motorboat. Vetus make good use of a specially developed computer programme which ensures the determination of the exactly right propeller for your boat, with the aid of some (correct!) inormation which is required from the customer.
Three types of managnese-bronze propeller are available:
P3B: 3-blade suitable for displacement craft with speeds of up to 10 knots
P3C: 3-blade suitable for faster craft
P4E: 4-blade suitable for semi-planing boats with speeds of more than 16 knots
