CHAPTER 3
3.11 OPERATIONAL LIMITS
Engine trouble can arise if the engine is operated for a long time under overloaded
conditions at max RPM. Recommended “Max Cruising Speed” is at least 10% below full throttle of
3800 RPM. While running, pay attention to the engine gauges on the EVC display. A significant
change in temperature, oil pressure, or voltage should be investigated immediately, before the
engine is damaged.
OIL PRESSURE – tba
COOLANT TEMPERATURE – Normally between 167 and 180 degrees F.
OIL TEMPERATURE – This should normally be less than 230 degrees F, or
110 degrees Celsius.
CHARGING – Normally about 14 Volts when underway.
Depending on hull structure and engine installation, engine and hull resonance may be greater at
some speeds than others. This is normal and you will learn to pick the sweet spots. If you hear
any abnormal sounds, stop the engine and inspect.
If any warning lights or buzzers activate, stop the engine immediately.
Determine the cause and repair the problem before continuing to operate.
