USCG Exam PracticeMotors and generators
According to 46 CFR §183.320, each generator and motor installed aboard a vessel must be mounted in which manner?
- A. At the centerline of the vessel to minimize vibration
- ✓ Above the bilges to avoid splash damage and contact with low-lying vaporsCorrect
- C. Below the waterline to lower the vessel's center of gravity
- D. In a sealed, watertight compartment to prevent moisture intrusion
Why B is correct
46 CFR §183.320(a)(2) requires each generator and motor to be mounted above the bilges to avoid damage by splash and to avoid contact with low-lying vapors. Mounting below the waterline or in a sealed compartment is not prescribed and would conflict with the ventilation requirement of §183.320(a)(1).
