Science of Silence
These silencers are made from enormously strong filament wound tube, giving the maximum possible protection if the exhaust back-fires.

Every unit is pressure tested before being gel-coated. They must be installed within 5° of horizontal.

In-Line silencers are used where the engine is well above the water-line, or where a high-riser has been fitted to achieve a 1 in 8 gradient from the engine to the transom outlet.

They are simple to specify and fit, and ideally need to be 500m to 1m behind the engine.

The internal design requires the exhaust gases and water to bubble through a layer of water on the bottom of the silencer to reduce noise.

They offer excellent noise reduction and are widely used on both pleasure and commercial engines.
