Hose connections

- To ease the fitting of the hose to the hose connector, use only wa-
ter and/or soap, NOT grease or products containing oil.
- Fit each hose connection with 2 stainless steel 12 mm (0.5") wide
hose clamps.

Installation examples

Exhaust systems with an exhaust silencer type LP/LSS/LSG, and si-
lencer type DEMPMP, goose neck type LT and a transom connection
are shown on page 15.
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 ex-
haust silencer) will run back to the exhaust silencer.
3.1 Prevention of syphoning (drawings 3 & 4)
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 bet-
ween 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 exhaust silencer.
