Why is my telltale stream weak or missing?

The tiny telltale passage often clogs with salt or bugs, which is an easy fix. A weak stream can also mean a worn impeller, so it is worth checking right away.

Should I flush my outboard after every trip?

Yes, a freshwater flush after every saltwater run helps keep salt from building up inside the cooling passages.

Can a stuck thermostat cause overheating?

Yes. A thermostat stuck closed blocks water flow and causes overheating, while one stuck open can make the engine run too cool.
