The engines have wet replaceable cylinder liners which
are cooled by fresh water.
The turbo-compressor supplies fresh air to the engine
during the induction stroke. Air is supplied under pressure,
resulting in a greater degree of volumetric efficiency. The
cylinders thus receive a greater quantity of air and conse-
quently more oxygen per stroke. In consequence the
amount of fuel injected can also be increased, which leads
to increased output.
The turbo-compressor is lubricated from the engine lubrica-
ting system and cooled from the fresh water cooling sys-
tem.

In order to further increase the supply of oxygen, the air to
the engine is cooled down by an after-cooler located after
the compressor at the intake manifold.
The Aquamatic models are provided with a hydraulic pump
and a special connection flange at the reverse gear. Other-
wise they are similar to the inboard engines. The hydraulic
pump, fitted at the rear side of the engine auxiliary drive
gear casing, close to the fuel injection pump coupling,
supplies oil under pressure to the power cylinder acting on
the lower, steerable part of the outboard drive. This results
in easy and effortless steering of the boat.
