Proper fueling procedures are very important in preventing onboard fires. Gasoline vapors are heavier than air and can spread rapidly into enclosed spaces. You should check the bilges and all closed compartments for gasoline vapors. The sniff test is the most effective method for detecting fuel leaks.

Tip: Always use the 'one-third rule': one-third of your fuel to get out, one-third to get back, and one-third in reserve.

1. Secure boat to the dock. boating safety course fueling graphic

2. Switch off engine(s).
3. Extinguish all open flames.
4. Do not use electrical switches.
5. No smoking.
6. Ports, hatches, and doors closed.
7. Portable tanks should be refueled ashore.
8. Make certain all passengers are ashore.
9. Determine quantity of fuel required.
10. Hold hose nozzle firmly against fill pipe opening.
11. Do not overfill. Prevent fuel from falling into the water during fueling. This can harm the marine environment.
12. Wipe up all spillage.
13. Open ports, hatches, and doors to ventilate.
14. Turn blower on for four minutes minimum.
15. Do the sniff test.
16. Start engines(s).
17. Re-board Passengers.
18. Untie from dock and cast off.

Protecting the Environment

It is not uncommon to see a small fuel sheen on the water surface near boats. Although it may only be a tiny amount from some boats, the cumulative impacts can be damaging to marine life. Once in the marine environment, oils and fuels have a tendency to accumulate in bottom sediments and concentrate in marine organisms. These harmful substances commonly enter the marine environment through bilge pumping or fueling. Don't add to the problem by overfilling your tanks.

Maintenance

Keep engine well tuned
Use correct propeller and check for damage.
Be sure engine is adequate for boat.
Use proper oil mix in motor.
Keep hull clean to reduce friction.

On the Water

Drain all water before leaving dock.
Distribute weight evenly and don’t overload.
Shut off engine when at dock or at rest.
Make fewer turns so as to not increase motor load.
Plane smoothly and quickly at take off then throttle back to cruising speed.
Plan fishing spots ahead of time and use trolling motor for minor changes in location.
