Stainless Steel Exhaust Risers
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.
High Rise Spray heads
Many engine manufacturers make a standard spray head for use when a high riser is not needed, If not Halyard can help. We can also produce spray heads with particular spray patterns for installations where cooling is critical.
Modular spray head and high riser
This modular spray head rotates at three points along its length, so that the riser can be incorporated in the exhaust in the easiest possible way. Once positioned, special clamps on each joint are tightened to fix the position permanently, and the heat resisting jackets are fitted.
Halyard High Risers combine two features: They raise the engine exhaust outlet to increase the gradient on the exhaust system, and they have a carefully calibrated range of water spray holes sized to make water jet into the exhaust gases at full power to maximise the cooling effect. Each is fabricated from 316 stainless to the highest standards. Many of the surfaces are polished, and each is equipped with heat protecting jackets tailored for the particular unit.
The make-up of a high riser is shown below. Each system is assembled to suit the particular engine flange and exhaust diameter.

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 |
