Exhaust, Silencer, BESPOKE SYSTEMS, SEPARATORS from Halyard etc.

Fortunately, the heat problem can be overcome and noise greatly reduced by injecting water into the exhaust pipe just behind the engine. Thus we have what's known, quite logically, as a wet, or 'water injected' exhaust. There are other advantages. The reduction in temperature means that the exhaust system can be made of something other than steel, saving considerable cost and weight and reducing vibration. Special rubber exhaust hose can be used to join straight lengths of tubing, and in smaller boats it can make up the entire exhaust run. Exhaust hose is also useful as a flexible joint between the engine and the exhaust system proper.

Interchanging Exhaust Alert and Sea Strainer Alarm.
Sensors for the Sea Strainer Alarm and the Exhaust Alert system can be interchanged using standard components, allowing systems which monitor both excess temperature in the exhaust system and blocked raw water supply. Please ask our Technical Staff for details. Dual station helm displays are also available.

WATER INJECTION HIGH RISERS

The achievement of effective cooling patterns in water injection elbows/sprayheads is an art. They must work at full power but still be effective at low revs when the water pump output is reduced.

We design and produce beautifully crafted modular high-rise injection systems for simple installations, or complex and sophisticated structures which must drop straight into position on craft thousands of miles away. Each one is the product of our design team working carefully with the customer.

Halyard Stainless Steel Exhaust Thru-hull Flapper H002524

When the Halyard Exhaust Thru-Hull Fitting was designed, we set out to achieve a make of product which was infinitely stronger than the plastic and GRP units on the market – and tougher than most stainless units.
The Halyard Thru-Hull uses 3mm thick 316 stainless to ensure that the risks of damage when manoeuvring a craft are reduced to the absolute minimum. All units are designed so that the flap, at rest, is shrouded by the stainless rim to prevent damage if the vessel nudges a harbour wall.

Through Hull Fittings – Neoprene Flap
Units to accept exhaust hose up to and including 100mm (4") hose have neoprene flaps. Each has a really generous tail allowing "T" bar exhaust hose clamps to be used to secure the hose. Smaller sizes have 3 countersunk fixing holes. The 90mm and 100mm (3.5" and 4") units have 4 bolt holes and a bolting flange which fits right around the unit inside the hull.
Through Hull Fittings – Stainless Flap
Units from 125mm (5") upwards all have stainless flaps lined with neoprene. All have tails with plenty of space to use proper "T" bar clamps to secure the hose. Between 4 and 8 bolt holes are provided and all units have bolting flanges to fit around the unit inside the hull. Sizes to suit up to 300mm (12") hose are currently manufactured, and they are a normal stock item up to 254mm (10").
