During the warmup period, scan the instrument panel for
correct operation of all systems. Oil pressure should read 35
to 65 lbs. Water temperature should gradually increase to the
normal controlled level of 140-160 degrees on direct water
cooled models, 180-200 degrees on fresh water cooled
models. Alternator charge output should be indicated on the
ammeter by the needle indicating toward the (+) side of zero.
IF EQUIPPED WITH A VOLTMETER, THE VOLTAGE
SHOULD GRADUALLY RISE TO APPROXIMATELY
13.5 VOLTS, AND REMAIN THERE WHILE THE
ENGINE IS OPERATING.
Break In
DO NOT OPERATE AT SUSTAINED FULL THROTTLE
DURING THE FIRST 5 HOURS OF OPERATION.
DO NOT OPERATE AT HIGH RPM'S IN NEUTRAL.
After the engine is thoroughly warmed up, and the boat is
underway, open the throttle wide until full RPM's are
reached. DO NOT EXCEED MAXIMUM RPM. (RPM's
should cease climbing after 10 to 20 seconds.) Reduce
throttle to 2,800 to 3,000 RPM, and cruise at or below the
speed for 1/2 hour. Reduce speed to idle, open throttle wide,
and operate at that speed for approximately 1 minute; reduce
to cruise throttle for a few minutes and repeat. (Bringing the
engine from idle speed to full throttle will load the engine
and assist in seating the piston rings.) This cycle can be
repeated from time to time during the first 5 hours of
operation, but full throttle should not be sustained for more
than 1 to 2 minutes.
FOLLOW THE PROCEDURE ONLY WHEN
CONDITIONS ARE SUCH THAT IT CAN BE DONE IN
COMPLETESAFETY.
DO NOT ATTEMPT TO BREAK IN AN ENGINE BY
PROLONGED IDLING OR RUNNING IN AT THE
DOCK.
During the early part of the break in period, correct propeller
selection can be confirmed. (With a normal load aboard, the
engine RPM's should reach, but not exceed, maximum
RPM's as listed under specifications for your model.)
During the break in, water temperature should be watched
carefully, and speed reduced if overheating becomes evident.
