Hose connections

In to order to best connect the hose to the waterlock, the top por-
tion of the waterlock can be turned in a 360° radius.
The top portion should be turned as follows:
1 Loosen the clamping ring (A) by unscrewing the M6 bolts
2 Pull the top portion of the waterlock upwards
3 Turn the top portion to the desired position
4 Let the top portion down again
5 Re-attach the clamping ring (A) by screwing the M6 bolts back in
using a 2 Nm tightening torque
Ensure that the O-ring is properly centred!
Screw on the M6 bolts at the same time.
Make sure the top part is not out of position!

Fitting the hose

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.
2.6 Sensor for temperature alarm
A sensor for a temperature alarm can be fitted in the exhaust pipe.
A sensor for a temperature alarm can also be fitted in the exhaust
silencer connector. The 'IN' connector on the exhaust silencer has
two circular areas. These are intended for fitting the temperature
sensor. Drill in one of these areas a hole of the correct size. Fit the
sensor with a lock nut and, after fitting, check that the exhaust
silencer is completely liquid and gas-tight.

Installation example

On p. 15, you will find a depiction of an exhaust system with a water-
lock of type MGP / MGS / MGL and a transom exhaust connection.
When the engine is stopped, any water which is still in the exhaust
pipe (between the highest point in the exhaust system and the
waterlock) will run back to the waterlock.
3.1 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 fitting an air vent (with valve) in the coolant water hose
between the engine block and water injection point 'C' .
4 Maintenance
• Check all hose connections for gas and water leaks regularly.
• Before the winter lay-up, drain the waterlock. The waterlock has a
drain plug for this purpose.
