if safe boating conditions permit, operate the
engine in gear at less than 1/2 (half) throttle
(3000 r/min.).
NOTE:
You may throttle up beyond the recommended
operating range to plane your boat, then imme-
diately reduce the throttle to the recommended
operating range.

the engine in gear at 4000 r/min. or at three-
quarter throttle. Avoid running the engine at
full throttle.
CAUTION

High speed without sufficient warm-up
may cause severe engine damage such
as piston seizure.
3. Remaining 7 hours:
Safe boating conditions permitting, operate
the engine in gear at desired engine speed.
You may occasionally use full throttle; how-
ever do not operate the engine continuously
at full throttle for more than 5 minutes at any
time.
NOTE:

you may use full throttle; however do not oper-
ate the engine continuously at full throttle for
