Installing the transom exhaust connection
Fit the transom exhaust connection at such a position that with
the ship fully laden, the outlet is still at least 5 cm (2") above
the waterline.
In order to install the transom exhaust connection so that it
remains watertight, apply marine adhesive sealant between the
flange of the transom connection and the transom.
The exhaust hose on the transom exhaust connection can be
fitted without hose connector.
Type TRCON
Maximum transom wall thickness at the place where the tran-
som connection is fitted, is 40 mm (1.6").
Type TRCON is available in the diameters 65 mm (2.4"), 75 mm
(3.0"), 90 mm (3.5") and 110 mm (4.3").
Type TC
The type TC transom exhaust connection is fitted with a non-
return valve. This prevents water from aft, caused by reversing,
quickly stopping the ship or waves from aft, from entering the
exhaust system.
The maximum wall thickness of the transom, where the transom
connection is fitted, may be 25 mm (1").
Fit the transom exhaust connection with the 'large' plain wash-
ers supplied.
Exhaust pipe
In order to ensure the proper drainage of the coolant water
injected into the exhaust pipe, the pipe must be installed with a
slope downward over its whole length from the water injection
point to the exhaust silencer.
During operation, the exhaust pipe will contain water. This will
increase its weight considerably, so support the exhaust pipe
properly.
The exhaust pipe from silencer to transom connection must be
installed in such a way that:
- The highest point in the exhaust pipe should not be more
than 150 cm (60") above the underside of the exhaust
silencer.
- The length of the section between the exhaust silencer and
the highest point, should not exceed 300 cm (120").
Hose connections
To ease the fitting of the hose to the hose connector, use only
water and/or soap, NOT grease or products containing oil.
Fit each hose connection with 2 stainless steel 12 mm (0.5")
wide hose clamps.
Sensor for temperature alarm
A sensor for a temperature alarm can be fitted in the exhaust
pipe.
Exhaust systems 90 mm - 150 mm
Installation examples
Exhaust systems with an exhaust silencer type LP , goose neck
type LT and a transom connection are shown on page 16.
Entry of water from the aft is almost completely prevented by
the extra height difference in the goose neck.
When the engine is stopped, any water which is still in the
exhaust pipe (between the highest point in the exhaust system
and the exhaust silencer) will run back to the exhaust silencer.
Prevention of syphoning (drawing 2)
If the water injection point 'C' is below, or less than 15 cm (0.6")
above the waterline (also when the ship heels under sail), there
is a risk that when the engine is stopped, the coolant water
will enter the engine due to syphoning. This syphoning can be
prevented in two ways:
By creating an air vent system in the coolant water hose
between engine block and water injection point 'C', by fitting
an air vent with air vent pipe, for example.
By creating an air vent system in the coolant water hose
between engine block and water injection point 'C', by fitting
an air vent with air vent pipe, for example.
Maintenance
Check all hose connections for gas and water leaks regularly.
Before the winter lay-up, drain the exhaust silencer. The exhaust
silencer has a drain plug for this purpose.
Transom exhaust connection TC
Check the non-return valve for proper function at least once a
year.
