NOTICE
When fueling at a marina, DO NOT over fill.
Fuel may spill into the water.
Avoid overboard spills. Be alert. The fuel nozzle
should automatically shut off when using an
automatic shut off nozzle. Be ready in the event
it does not or if you are using a different type of
nozzle for dispensing fuel. DO NOT TOP OFF.
Fuel Systems - Section I
After fueling, close the fill cap, and wash the areas
around the fuel fill cap. Residual fuel left on the deck
and hull sides can be dangerous and will yellow the
fiber g lass. It can also damage the tape stripes and lo-
gos. Care should be taken, when cleaning, to prevent
contaminating the fuel vent and deck fill. Cleaning with
only mild soapy water is recommended.
E. Fuel Vents - Domestic Models
On the SL series models, separate thru-hull P-trap
fuel vents are installed. See Figures I7. While the tank
is being filled, the air displaced by the fuel es c apes
through the vent overboard.

When it comes to maintenance of the fuel vent the
manufacturer has provided the following information
and maintenance instructions.
You will know the vent needs maintenance if vapor
rushes into or out of fuel tank when you open deck fill
cap. You may also notice difficulty while fueling (back-
splash or pump shutting off continuously during fill).
Debris and spider webs can block the vent, especially
after storage. Use these steps to clean vent screen
before and after storage, or at least once a year.
This maintenance should be done while the boat is
out of the water. This way you do not risk losing parts.
1. Use a 3/16" (5mm) hex wrench to turn cap off
counter-clockwise. Set cap aside for re-installation
2. When cleaning, DO NOT allow debris to fall down
the vent tube into tank.
3. Remove screen and clean with solvent or air
pressure. Be sure not to puncture the screen.
