1.2 RAIDER BREAK-in PROCEDURES
CAUTION
Failure to follow the Break-In Procedure in Owner’s Manual and special fuel mixture
requirements for break-in may lead to serious engine damage and shortened engine life.
To prevent serious engine damage and ensure long engine life, new engines, used engines with
new powerhead, used engines with newly rebuilt powerhead, and engines coming out of storage
must be run for a period of 10 hours in accordance with the break-in procedure.
First 10 Minutes
• Operate the engine at minimum idle speed
• Verify a steady stream of water from the cooling water check port and idle port on the engine,
indicating the water pump is functioning properly.
Next 50 Minutes (0.16 to 1 Hour)
DO NOT operate the engine above 1/2 throttle.
DO NOT maintain a constant throttle setting. Vary engine speed from 1/4 to 1/2 throttle every 15
minutes.
NOTE
For boats which come onto plane easily, use full throttle to quickly accelerate onto plane; then
immediately reduce throttle to 1/2 and maintain this speed.
Next Hour (1 to 2 Hours)
• Use full throttle to quickly accelerate boat onto plane; then immediately reduce throttle to 3/4 and
maintain this speed.
• At intervals, run engine at 3/4 throttle for 1 - 10 minutes; then return to 1/2 throttle for a cooling
period.
• Vary engine speed every 15 minutes.
• Check for water discharge from cooling water check port
Next Eight Hours (2 to 10 Hours)
• Run engine at 3/4 throttle.
• For short periods of time, run engine at full throttle and then reduce speed back to 3/4 throttle. As
this part of the break-in period progresses, open to full throttle for longer and longer periods of time,
but never longer than 5 minutes.
• Vary engine speed every 15 minutes.
DO NOT exceed the Full Throttle RPM Range of the engine. See Engine Specifications.
After Break-in
• Re-torque cylinder head bolts to specification after engine has been run and cylinder head has
cooled to the touch.
