Boat-In-The-Water Tests
IMPORTANT: DO NOT perform the following with boat in a test tank or tied to dock.
ENGINE INITIAL BREAK-IN PROCEDURE
It is especially important that the following procedure be used on new diesel engines. This
break-in procedure allows the proper seating of the pistons and rings, which greatly
reduces the likelihood of low hour problems.
IMPORTANT: It is recommended that the boat not be accelerated hard until this
procedure has been completed.
Initial Break-In Procedure is as follows:
1. Follow instructions: Pre-lubricate the turbocharger and engine. To do this, hold the
STOP switch toggle lever DOWN while you simultaneously turn the key switch to
START position for 15 seconds.
This will rotate the starter motor and engine / oil pump. During this process the engine will
not run because no fuel is injected. Allow the starter motor to cool down for one minute
and repeat the above described process. Pre-lubrication is complete when oil pressure is
shown by instruments.
To avoid overheating the starter motor, do not engage starter motor for more than 15
seconds each time.
2. Start engine and operate at idle until coolant has reached minimum operating
temperature 65° C (150° F).
3. Operate the engine in gear for 3 minutes at each of the following rpms: 1200 rpm, 2400
rpm e 3000 rpm.
4. Ooperate engine in gear for 3 minutes at each of the following rpms: 1500 rpm, 2800 rpm
e 3400 rpm.
Operate engine in gear for 3 minutes at each of the following rpms: 1800 rpm, 3000 rpm
5.
and Maximum Rated Full-Throttle rpm.
