Poor Ventilation

Under certain running or wind conditions, permanently enclosed or canvas enclosed cabins or cockpits with insufficient
ventilation may draw in carbon monoxide. Install one or more carbon monoxide detectors in your boat.
Although the occurrence is rare, on a very calm day, swimmers and passengers in an open area of a stationary boat that
contains or is near a running engine may be exposed to a hazardous level of carbon monoxide.
1. Examples of poor ventilation while the boat is stationary:

Important Operation Information

Launching

IMPORTANT: Install the bilge drain plug before launching the boat.

Duty Cycle Rating Requirements

IMPORTANT: Damage caused by incorrect application or failure to operate the power package within the specified operating
parameters will not be covered by the Mercury Marine Limited Warranty.
Mercury Diesel engines must be used in applications that meet the operation specifications indicated by a Mercury Diesel
product application engineer. The power package must be equipped with a gear ratio and propeller that allows the engine to
operate at wide open throttle (WOT) at the engine's rated speed (RPM). Use of Mercury Diesel engines in applications that do
not meet specified operational parameters is not approved.
High‑Output Rating
A High‑output rating applies to pleasure (nonrevenue generating) applications that operate 500 hours or less per year, where
full power is limited to one (1) hour out of every eight (8) hours of operation. Reduced power operation must be at or below
cruise speed (RPM). Cruise speed is dependant on the engine's maximum rated speed (RPM).
