1. Engine frame
The engine frame must be solid and able to absorb all
the dynamic stress as well as the weight of the engine. It
must be connected to the hull by a big a surface area as
possible.
The engine must not be at an angle of more than 7° when
the boat is stopped.
2. Propeller shaft
The choice of propulsion system must be made according
to the restrictions arising from the engine and the boat.
3. Water exhaust box (waterlock)
The waterlock must be positioned as close to the engine
and as low as possible. Its volume must be of 20 litres
minimum. The maximum allowable back pressure is 28.7
kPa (4.162 PSI)
4. Hull outlet
The hull outlet must be located 15 cm above the water line.
The tube between the exhaust box and the hull outlet must
form a swan-neck shape to avoid any water getting into the
exhaust system through the hull outlet.
5. Anti-siphon valve
This is obligatory on boats whose engine is below the
waterline. The anti-siphon valve must be installed at the
end of the seawater system before injection in the exhaust
elbowandmustbepositionedabovethewaterline,between
0.5 and 2 meters.
6. Seawater filter
This must always be positioned at least 15 cm above the
waterline.
7. Through-hull valve
