Jet Installation

Start in Gear Protection

Starting the engine with the drive in gear can cause serious injury or death. Never operate a boat that does not have a
neutral‑safety‑protection device.
The remote control connected to the outboard must be equipped with a start in neutral only protection device. This prevents the
engine from starting in gear.

Selecting Accessories for Your Outboard

Genuine Mercury Precision or Quicksilver Accessories have been specifically designed and tested for this outboard.
Some accessories not manufactured or sold by Mercury Marine are not designed to be safely used with this outboard or outboard
operating system. Acquire and read the installation, operation, and maintenance manuals for all selected accessories.

Fuel System

Fuel Tanks

Portable Fuel Tank
Select a suitable location in the boat within the engine fuel line length limitations and secure the tank in place.
Permanent Fuel Tank
Permanent fuel tanks should be installed in accordance with industry and federal safety standards, which include
recommendations applicable to grounding, anti‑siphon protection, ventilation, etc.

Integrated Fuel Demand Valve (iFDV) Requirement

Whenever a permanent pressurized fuel tank is used, an integrated fuel demand valve is required to be installed in the top of the
fuel tank via an O‑ring seal.
The integrated fuel demand valve prevents pressurized fuel from entering the engine and causing a fuel system overflow or
possible fuel spillage.
The integrated fuel demand valve has a manual release. The manual release can be used (pushed in) to open (bypass) the valve
in case of a fuel blockage in the valve.
Low Permeation Fuel Hose ‑ Outboard
To meet the Environmental Protection Agency (EPA) regulations, any outboard engine built on or after January 1, 2009, for sale,
sold, or offered for sale in the United States must use a low permeation fuel hose between the fuel tank and the first fuel line
connection on the outboard.
• Low permeation fuel hose is USCG Type B1‑15, or Type A1‑15 defined as not exceeding 15 g/m²/24 h with CE 10 fuel at 23 °C
as specified in SAE J 1527 – marine fuel hoses.
• The rule defines it as the first connection on the engine, which means the stub hose or pigtail that is factory installed does
not need to be low permeation.
• If the OEM/boatbuilder supplies the hose, they should use low permeation hose.
• Outboard engines manufactured prior to January 1, 2009 that are installed on boats after January 1, 2009 are not required
to use low permeation fuel hose.
• If the OEM/boatbuilder has inventory of non‑low permeation hose, they are allowed to use it up prior to changing over to low
permeation hose. Stockpiling is not allowed.
• Any non‑low permeation fuel hoses and hose kits that were produced prior to January 1, 2009, can still be sold as service
parts until inventory is depleted. However, they cannot be used to rig engines produced in 2009 and beyond.
