Repair :

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.

Propellers are normally supplied disc ground but can be polished if necessary. All propellers are statically balanced, keyward and taper bored to customers’ requirements.

Sterngear (Type D.J. Mark 4):

This Sterngear was designed mainly for the steel narrow boats used by the hire fleet operators of the inland waterways.

Each set is made up with an aft steel type WELD IN gland, steel stern tube fitted with oilite bearings at each end and with lubrication nipple fitted, forward flange and stuffing box cast from Manganese Bronze or Gun Metal and fully machined.

One of the advantages of this type of Sterngear is that at the end of a season the tube can be removed complete with its bearings and a replacement fitted with the minimum down time and a great saving in cost against normal types of stern tubes and bearings.
