Break In Procedure

Make sure all your passengers are properly seated before starting
the break in procedure. After the engine is thoroughly warmed up
and you have driven the boat into a large open area, advance the
throttle to wide open until the maximum rpms are reached. Do not
exceed 5,000 rpm. Reduce the throttle to 2,800-3,000 rpms and
cruise at or below this speed for 30 minutes. Reduce the speed to
idle, advance the throttle to wide open and operate at that speed
for one minute; reduce to the previous cruising speed for a few
minutes and repeat. Accelerating from idle speed to wide open
assists in seating the piston rings. This cycle can be repeated from
time to time during the first five hours of operation. DO NOT
operate engine at full throttle for longer than 1-2 minutes.

Propeller Selection

The maximum rpm of the engine at full throttle under normal load
conditions can be controlled by propeller pitch, diameter and
design. It is essential the propeller does not underload or overload
the engine.

Propeller Overloading,

results in low rpms at wide open throttle

will give poor performance, poor fuel economy and eventually
result in engine damage.

Propeller Underloading,

if operated with a propeller that has too

little pitch or diameter, poor performance will result.

Getting Underway

Sport

Follow these procedures only when

conditions are such that you can drive the boat safely.

!

WARNING

Do not attempt to break in an engine by

letting it idle at the dock.
