Fuel-Water Separator & Drain
Fuel-Water Separator
Two Yamaha Fuel - Water Separators are installed
between the fuel tank and engine on your 280 DC
model. The new, improved 10-micron filter
provides superior filtration ahead of the engine's
on-board filters and injectors. Large filtering and
water capture areas maximize filtration while
maintaining adequate flow rate for larger engines.
The fuel separator can be checked by removing it
from the mounting bracket and dumping it into an
approved waste collection device. If there appears to be an excessive amount of water,
the filter component should be replaced. See your authorized Cobia Dealer for
replacement parts. Refer to Fuel System diagram, page 38.
Garboard Drain Plug
The garboard drain plug is the small metal plug located at
the lowest point on the hull, at the bottom of the transom
right above the keel. The drain has been designed so that it
can be loosened by hand while the hull is out of the water
for draining. This allows the plug to stay in contact with
t
he surrounding frame so you’ll never misplace or lose it. You can completely remove
the insert by pulling back and continue turning in a counter-clockwise motion. It is
manufactured with a rubber seal in place to ensure your bilge is watertight. Always
make sure before putting the boat in the water that this plug is hand tightened firmly.
Excess water in the bilge may be an indication of a problem with this plug or the
automatic bilge pump. Refer to the Water Drain System diagram on page 37.
Maintenance Note: Yamaha recommends replacing the 10-
micron fuel filter on new boats after the first 10 hours or 1 month of
operation and every 50 hours or every 6 months thereafter.
In
areas of high humidity where water in fuel supplies is a problem or
extensive engine operation occurs, more frequent replacement
may be necessary.
