OPERATION
eng
55
The engine automatically receives extra oil during the first hours
of operation. For most boaters this extra oil mode will be
complete in about ten hours.
BREAK-IN PROCEDURE
1. For the first hour of operation, allow the engine to warm up
for 30–60 seconds.
a. Run the engine at varied throttle settings, the majority of
the time between 3000 and 4500 RPM or three‑quarter
throttle.
b. Change engine speed approximately every two minutes,
and avoid continuous operation at idle speed for more
than ten minutes. Short bursts of full throttle for periods
up to ten seconds are acceptable.
c. Avoid trimming the outboard out (up) beyond a vertical
trim position during operation.
NOTE: It is the driver's responsibility to always drive in a safe
manner. Improper trim angle of the outboard when driving at
high speed can be difficult and dangerous. The purpose of
specifying trim angle is to help guide the operator in determining
how to put the proper load on the engine. They are intended to
be guidelines and do not suggest or require unsafe boat
operation.
2. For the next three hours of operation, change engine speed
every ten minutes.
Starting the Engine
Before starting, read the pre‑starting check list, special operating
instructions, and engine break‑in procedure in the
Operation
Section.
NOTICE
Without sufficient cooling water, the engine, the water pump,
and other components will overheat and suffer damage.
Provide a sufficient supply of water to the water inlets during
operation.
