Fuel Additives; Fuel Requirements; Avoiding Fuel Flow Restriction; Low Permeation Fuel Hose Requirement - Mercury 200 OptiMax DTS Manual

Fuel Additives

To minimize carbon deposit buildup in the engine, it is
recommended to add Mercury or Quicksilver Quickleen Engine
Treatment additive to the engine's fuel at each tank fill
throughout the boating season. Use additive as directed on
container.

Fuel Requirements

Do not use premixed gas and oil in this engine. The engine
automatically receives extra oil during engine break‑in. Use a
fresh supply of the recommended gasoline during engine
break‑in and after engine break‑in.

Avoiding Fuel Flow Restriction

IMPORTANT: Adding components to the fuel supply system
(filters, valves, fittings, etc.) may restrict the fuel flow. This may
cause engine stalling at low speed, and/or a lean fuel condition
at high RPM that could cause engine damage.

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/gm²/24 h with CE 10 fuel at
23 °C as specified in SAE J 1527 ‑ marine fuel hose.
EPA Pressurized Portable Fuel Tank
Requirements
The Environmental Protection Agency (EPA) will require portable
fuel systems that are produced after January 1, 2011 for use with
outboard engines to remain fully sealed (pressurized) up to
34.4 kPa (5.0 psi). These tanks may contain the following:
