IMPORTANT OPERATING INSTRUCTIONS
FOR GENERATOR OPTION ONLY
Caution is needed when operating or starting a generator on Four Winns 278 Vistas equipped with
hydro-lift mufflers. Water can accumulate in the muffler if engine fails to start. Prolonged cranking
of the starter will pump water into the muffler system. Each additional attempt to start (that fails)
places more water into the exhaust, and will back up into the manifold and flow into the cylinders.
If the starter does not crank over the engine (after continued attempts have failed), there may be
water backed into a cylinder. This condition may be mistaken as a dead battery and immediate
action is necessary to prevent engine damage.
If the generator is hard starting, Four Winns recommends removing the drain plug in the muffler to
allow water to drain and have engine tuned up or repaired as soon as possible. Once the engine is
started, reinstall the drain plug.
DO NOT leave boat unattended with plug removed. Water may enter boat from
overboard.
To locate the drain plug or muffler, refer to the generator manufacturer's literature supplied with this
manual. If the generator does take on water, it is very important that immediate action is taken
to prevent engine damage. Contact your Four Winns or OMC dealer for assistance.
