7. Engine Performance Test
• All gauges and test equipment should be observed as frequently as possible
to allow the operator to react quickly to any discrepancy displayed. The
operator must also listen for unusual sounds, feel for unusual vibrations,
smell for signs of fuel, smoke, etc. and look for any sign of abnormal
operational characteristics.
• Verify normal operation and readings on all gauges.
• When conditions permit, accelerate to bring the boat on plane and to a
cruising speed of 3600 RPM. While frequently observing the gauges,
operate the boat at this speed for fi ve minutes.
• After fi ve minutes at 3600 RPM, move the throttle to wide-open-throttle
(WOT) and run at this speed (not to exceed 30 seconds) until the RPMs
have stopped increasing. Note and record the WOT RPM and fuel pressure
at WOT. Reduce the throttle to 3600 RPM.
• Operate the engine(s) at 3600 RPM for an additional 10 minutes while
frequently observing the gauges.
• Return to idle.
• For twin engine applications: Shut off both engines, then relieve the
fuel pressure and disconnect the fuel gauge from engine #1, connect
the fuel gauge to engine #2, re-start the engines, then as conditions
permit, accelerate to bring the boat on plane and to a cruising speed
of 3600 RPM. Operate the boat at this speed for approximately one
minute, then move the throttle to wide-open-throttle (WOT) and run at
this speed (not to exceed 30 seconds) until the RPMs have stopped
increasing. Note and record the fuel pressure at WOT for engine #2.
• Return to idle.

8. Diacom Record of Engine Performance (Optional)
• Record the following water test for your records, using the Diacom ‘Record’
feature. This recording is to be made after all defects, if any are found, have
been corrected. The record time for this procedure will easily fi t on a 3 1/2”
fl oppy disk making it easily accessible for future retrieval, reference and
storage.
NOTE: 2007 Engines: For Twin engine applications, Diacom will have to be
connected to the other engine and the procedure repeated so you
will have a recording of both engine’s parameters.
1. Start the Diacom record function.
2. Idle for 10 seconds.
3. Run at 1,000, 2,000, 3,000, and 4,000 RPMs for 10 seconds each.
4. Return to idle for 10 seconds.
5. Accelerate to 3600 RPM and run @ 3600 RPM for 30 seconds.
6. Accelerate to WOT and run at WOT until the RPM’s stop increasing (not to
exceed 30 seconds).
7. Return the throttle(s) quickly to idle and allow the engine(s) to idle for 10
seconds, then stop the recording.
8. Save the recording, using the engine(s) serial number as the fi le name.
• Return to the dock, check the engine(s) for leaks (water, oil and fuel) and
correct any leaks noted. Turn off the engine(s), recheck the fl uid levels in
the transmission(s) and engine(s) and correct as necessary.
• Review the test data and compare the results to the Master Engine
Specifi cation Sheet. If defects were noted, correct all, then retest the boat.
• Disconnect the test equipment and prepare the boat for customer delivery.
Check the compliance box.
