The exhaust gases of fuel-powered devices are extremely dangerous if exposure is prolonged. Over-exposure to carbon monoxide can be lethal.

  • Never leave the boat unattended when appliances are on, and regularly check that they function as they should.

  • Make sure that the cabin is sufficiently well ventilated. Keep ventila­tion ducts open.

  • Beware of engine exhausts. See 2.6 Carbon monoxide for details.

Gasoline fuel system

The engine runs on gasoline. The fuel filling inlet is labeled "Fuel". The fuel level in the tank can be monitored from the engine multi-function panel on the steering console (see section 4.3.1 Yamaha engine controls).

The gasoline fuel system is described in detail in the engine manufacturer's manual. Check the manual especially for:

  • Recommended fuel types

  • More detailed refueling instructions

  • Instructions for use and care.

EPA compliant fuel system

The boats for the United States market are compliant with the US Environmental Protection Agency (EPA)  regulations.

The boats are equipped with a carbon canister. The system captures gasoline fumes and prevents fuel overflow when refueling.

In addition, there is a fuel valve controlling the fuel supply to the engine. The fuel valve is located by the gasoline fuel filter.

Diesel fuel system

The diesel fuel system is available as an optional feature for powering a heater. The diesel fuel filling inlet is labeled "Diesel". The fuel level in the tank can be monitored from the engine multi-function panel on the steering console (see 4.3.1 Yamaha engine controls).

For instructions for use and care, see 4.11.1 Heater  and the manufacturer's manual.

LPG system

The Liquefied Petroleum Gas (LPG) system powers the gas cooker in the wet bar and in the cabin. This feature is available only for certain models.

For instructions for use and care, see section 4.11.3 Gas cooker.
