Break-ln Procedure
Severe damage to the engine can result by not complying with the Engine Break-
in Procedure.
FUEL REQUIREMENTS
Do not use pre-mixed gas and oil in this engine. Use straight gasoline during engine
break-in and after engine break-in. The ECM is programmed to signal the oil pump to pro-
vide additional oil (50:1 ratio) during the first 120 minutes of operation. The ECM will moni-
tor this period through its own internal clock. At the end of this period, the ECM will signal
the oil pump to go to a standard ratio of 300 – 400:1 @ idle and 60:1 @ W.O.T.
INITIATING ENGINE BREAK-IN SEQUENCE
Refer to Section 3C for proper procedures.
ENGINE BREAK-IN PROCEDURE (ALL MODELS)
Vary the throttle setting during the first hour of operation. Avoid remaining at a constant
speed for more than two minutes and avoid sustained wide open throttle.
