Re: mercury 4hp 2 stroke outboard noisy bearings
Noise is coming from main crank. It sounds either the roller bearing or one of the ball bearings. It is slightly noisy.
Is it common for it to fail quickly on these engines ? My engine is 19 years old and has hardly been used. I am suspecting bearings are rusty rather than worn.
Is it easy to take apart replace bearings and put together with basic tools?
I was given this engine but no service manual.
