How much water should come out from and outboard motor?

An outboard motor should expel a steady stream of water from the telltale, indicating that the cooling system is functioning properly. Generally, you should see a strong, continuous flow of water while the motor is running, especially at higher RPMs. If the water flow is weak or absent, it may signal a blockage or cooling issue that needs to be addressed. Regular maintenance and checks are essential to ensure optimal performance.
