Fuel Requirements
!
WARNING
Failure to comply with regulations can result in injury from fire or explosion. Electrical system components on this engine are
not rated as external ignition–protected (EIP). Do not store or use gasoline on boats equipped with these engines, unless
provisions have been made to exclude gasoline vapors from the engine compartment (REF: 33 CFR).
!
WARNING
Fuel leakage is a fire or explosion hazard, which can cause serious injury or death. Periodically inspect all fuel system
components for leaks, softening, hardening, swelling, or corrosion, particularly after storage. Any sign of leakage or deterioration
requires replacement before further engine operation.
!
WARNING
This engine requires diesel fuel. Mixing gasoline, gasohol, or alcohol and diesel fuel can cause serious injury or death due to
fire or explosion. Never mix gasoline, gasohol, or alcohol with diesel fuel.
IMPORTANT: Use of improper or water‑contaminated diesel fuel can seriously damage your engine. Use of improper fuel is
considered misuse of the engine, and damage caused thereby will not be covered by the warranty.
Grade 2‑D diesel fuel is required, meeting ASTM Standards D975 (or fuel rated Diesel DIN 51601), and having a minimum cetane
rating of 45.
The cetane number is a measure of the ignition quality of diesel fuel. Increasing the cetane number will not improve overall engine
performance, but it may be necessary to raise the cetane rating for low‑temperature or high‑altitude use. A lower cetane number
could cause hard starting and slower warm‑up, and could increase engine noise and exhaust emissions.
NOTE: If your engine suddenly becomes noisy after a fill‑up, you possibly received substandard fuel with a low cetane rating.
Sulphur content of the above fuel is rated at 0.50% by weight, maximum (ASTM). Limits may vary in countries outside of the United
States.
On engines that use high sulphur content diesel fuel, this will greatly increase:
•
Corrosion on metal parts.
•
Deterioration of elastomer and plastic parts.
•
Excessive wear of internal engine parts, particularly bearings, and corrosion and extensive damage to other engine parts.
•
Difficulty starting and operating the engine.
Recommended Fuels
NOTICE
The use of improper fuel can cause serious damage to the engine. Damage resulting from the use of improper fuel is considered
engine misuse and is not covered under the limited warranty. Use only the recommended fuel in the engine.

Diesel Fuel in Cold Weather
Unaltered diesel fuels thicken and gel in cold temperatures unless treated. Virtually all diesel fuels are climatized to allow their
use in the particular region for that time of the year. If it becomes necessary to further treat diesel fuel, it is the owner/operator's
responsibility to add a commercial standard brand of anti‑gel diesel fuel additive, following that product's directions.
