To assure the main propulsion turbine bearings are receiving the proper lube oil supply, you should check the _______________.

Alube oil strainer magnets

Bflow through the sight glass at the bearing

Cbull’s-eye in the gravity tank overflow

Dlube oil temperature at the cooler outlet

AI Explanation

The correct answer is B) flow through the sight glass at the bearing. To ensure the main propulsion turbine bearings are receiving the proper lube oil supply, you should check the flow through the sight glass at the bearing. This allows you to visually confirm that the lube oil is flowing properly to the bearing, which is critical for proper lubrication and cooling of the bearing surfaces. The other options are incorrect because they do not directly measure the lube oil flow to the bearing. Checking the lube oil strainer magnets, the bull's-eye in the gravity tank overflow, or the lube oil temperature at the cooler outlet would not provide a direct indication of the flow to the specific bearing in question.
