At Crowther Marine we also realise that sometimes damaged propellers and sterngear need immediate attention, that’s why we provide a comprehensive emergency repair service for all our products and for other manufacturers products alike, including bronze, aluminium and stainless steel propellers.
All our propellers are cast from the best quality Manganese Bronze or if required Nickel Aluminium Bronze to British Standard. We carry a comprehensive range of patterns of diameters up to 42” with various pitch dimensions. In all we have a range in excess of 450 patterns.
Propellers are normally supplied disc ground but can be polished if necessary. All propellers are statically balanced, keyward and taper bored to customers’ requirements. With the comprehensive range of patterns that we carry, it is normally possible for us to supply the exact propeller to your requirements.
