CXO300 OWNER’S MANUAL
5.5 EARLY USE BREAK-IN
Each CXO300 diesel outboard follows a run-in process prior to being shipped from the factory.
Nevertheless, Cox Powertrain recommends to limit load during a break-in period of 10 hours of operation,
as well as limiting or avoiding periods of extended idle where possible.
Following this process will ensure full performance and longevity is realized.
During the break-in period, adhere to the following guidelines:
1 For the first hour of operation, safe boating conditions permitting, do not exceed half control lever
travel.
2 For the second hour of operation, safe boating conditions permitting, do not exceed ¾ control lever
travel.
3 For the remaining of the first 10 hours, avoid running the outboard(s) at maximum power for longer
than 5 minutes at a time or idling the outboard(s) for more than 5 minutes at a time.
 NOTE
The above break-in guidelines may be ignored in the event of emergency or risk to safety.
Overly aggressive outboard operation during the first 10 hours can affect the longevity and
performance potential of your outboard(s) and may cause damage which could
invalidate your warranty.
5.6 WARM UP
Your powerhead is most efficient when within the warm operating temperature range.
When cold, both fuel consumption and mechanical wear are increased significantly and it is important
to follow the correct warm-up procedure by limiting powerhead speed and load until the correct
temperatures are achieved.
The helm display will show a cold indicator whenever outboard temperature is below warm. Avoid
exceeding 50% demand or 2,000rpm while the cold indicator is active.
 CAUTION
Do not exceed 2,000rpm or idle excessively before the cold indicator has extinguished.
 CAUTION
Severe damage to the engine can result by not complying with the engine break-in procedure.
