When lubricating a newly overhauled steel hub propeller, you should lubricate the propeller

after 10 hours of operation.

at the next 100-hour inspection.

after one to two hours of operation.

When lubricating a newly overhauled steel hub propeller, it is important to properly break it in. Lubricating it after one to two hours of operation allows the propeller to be fully broken in and ensures that all the internal components are properly lubricated. Waiting until the next 100-hour inspection or every 50 hours may not provide enough lubrication to keep the propeller functioning at its best. Additionally, waiting until after 10 hours of operation may cause excessive wear and tear on the propeller, potentially leading to costly repairs or replacements. Therefore, option C is the most correct answer.
