What is a prop deflector

Prop Deflector (aka prop guard) is a unique stainless steel propeller deflector also designed to protect the propeller without restricting the overall performance of the engine and craft at speed. Prop deflector is designed in the UK and manufactured by BH Fabrications.

Prop deflector construction

The construction is produced in marine grade stainless steel. The deflector bars are made from aerofoil shaped as an oval tube, which reduces the possibility of damage to the structure. Yet, it still offers incredible strength.

Prop Deflector was originally developed for the flood rescue sector and proved very successful in use by the rescue services, before coming into commercial and leisure market. It has been tested in extreme conditions and proved incredibly robust.

In test by the RNLI found that a craft using a prop guard achieving a speed of 30 knots lost less than 5% overall speed with no manoeuvrability issues.

The range

Our range of prop deflectors currently covers outboard motors ranging from 3-150hp. Each prop guard model is a tailored fit to each engine combination. Currently designed new models will increase our range further.
