Break In Period
Taking care to properly break in your new engine will pay o in
the long run. In our years of eld testing, we have proven that
an Indmar engine, when properly broken in according to our
simple procedures, will last longer, run better and have fewer
repairs over its lifetime.
Your new engine does not require an elaborate break-in
procedure. Just follow these simple instructions and you are
o to a great start.
The three (3) most important aspects of new engine break-in
are:
1. Avoid running engine at high speeds.
2. Do not carry a heavy load (passengers, gear, etc.).
3. Vary your boat speed during break-in. Don’t run at the same
RPM for a long period of time.
BREAK-IN STEPS
For the rst hour, do not exceed 2,000 RPM.
For the second hour, do not exceed 3,000 RPM.
For the next seven hours, do not exceed 4,000 RPM and vary
the RPM regularly
BREAK-IN TIPS
Avoid fast accelerations and don’t carry (or pull) a heavy load
during this period.
Always let engine warm up gradually before acceleration.
Check oil frequently. During the rst 50 to 100 hours, an
engine can use more oil than usual. Maintain oil at a proper
level at all times (do not overll).
Monitor transmission uid levels.
Report abnormal noises or vibrations to your dealer.
Keep an eye out for loose mountings, ttings, nuts, bolts,
and clamps.
During the BREAK-IN process, engine temperature should be
carefully monitored and speed should be reduced if overheating
is evident. ALSO, PLEASE REFER TO ENGINE OWNER’S
MANUAL FOR BREAK-IN INFORMATION.
NOTICE: PLEASE REFER TO ENGINE OWNER’S MANUAL for
maximum RPM and engine break-in procedure.
Do not exceed maximum RPM recommended for your
engine. Exceeding the maximum RPM may result in damage
to the engine.
Before starting your engine you must open the engine box
and check engine compartment and bilge for gasoline and
oil vapors.
