Enrichener System - Mercury 45 Jet 50-55 Service Manual

Enrichener System

The enrichener system provides the engine with extra fuel
charge for ease of starting cold engine. The system con-
sists of an electrically operated enrichener valve which is
connected by a hose to the intake manifold.
Fuel is gravity fed to the valve from the float bowl of the top
carburetor via a hose. When the ignition key is turned to the
"on" position and pushed in (and held in) current is sent to
the valve causing it to open, which allows fuel to pass thru.
The fuel passes thru a hose and is supplied to the engine
via fitting located in the intake manifold of the middle carbu-
retor. When the key (or choke button) is released, the valve
will return to the closed position. The valve can be operated
manually by pressing and holding button located at bottom
of valve.
