First-time operation

Engine break-in
NOTICE

Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in period is essential to al-
low the various components of the engines to
wear and polish themselves to the correct
operating clearances. This ensures proper
performance and promotes longer compo-
nent life.
(1) Check the engine oil level. (See page 134
for information on checking the engine
oil level.)
(2) Launch the boat and start the engines.
(See page 152 for information on starting
the engines.)
(3) For the first 5 minutes, operate with the
engines at trolling speed.
(4) For the next 30 minutes, operate with the
engines speed below 5000 r/min.
(5) For the next 1 hour, operate with the en-
gines speed below 6000 r/min.
After the engine break-in is complete, the
boat can be operated normally.
