Rudder Bush Material

The rudder bush material is ultra-high molecular weight (UHMW) polyethylene aka industrial grade polyethylene. According to Trafalgar Yacht Services, the bushes have always been made of this material, as specified on the Westerly drawings.

You may find an engineering firm close to you is able to make the bushes you want locally. If so, please let us know and we will add them to this list for the benefit of others. If you can't find a local engineer who can help you then we will hopefully have a growing list of firms that we believe can help. Either way, you should take the drawings to the engineers yourself as WOA cannot be involved in the order to production process. If you own a popular model (Centaur for example) you may like to use the WOA forum to find other owners who may agree among themselves to club-together to make an order for a larger number of bushes if that saves you money.

Trafalgar are still trading from home. They keep stocks of the shaft seals and are able to supply the correct seal for each model.

List of organisations able to supply can be found in the supplier list:
