Low Permeation Fuel Hose Requirement
Required for outboards manufactured for sale, sold, or offered for sale in the
United States.
• The Environmental Protection Agency (EPA) requires that any outboard
manufactured after January 1, 2009, must use low permeation fuel hose
for the primary fuel hose connecting the fuel tank to the outboard.
• Low permeation 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 hose.
Mercury Marine Validated Engine Mounting Hardware
IMPORTANT: Mercury Marine provides validated fasteners and installation
instructions, including torque specifications, with all of our outboards so they
can be properly secured to boat transoms. Improper installation of the outboard
can cause performance and reliability issues that can lead to safety concerns.
Follow all of the instructions relating to the outboard installation. DO NOT
mount any other accessory onto the boat with the fasteners provided with the
outboard. For example, do not mount TowSport bars or boarding ladders onto
the boat using the mounting hardware included with the outboard. Installing
other products onto the boat that utilize the outboard mounting hardware will
compromise the ability of that hardware to properly and safely secure the
outboard to the transom.
Outboards that require validated mounting hardware will have the following
decal on the transom clamp.
