I have a 25 hp Mercury 3 cylinders 4 stroke. I replaced the top bearing on the shaft. After reassemble I noticed up/ down play. This play may be about a 1/16 up/down. My question is this normal. thanks for your help
If the cone bearing is facing up and the race is facing down then the play is normal because then the motor is running that is what puts the pre-load on the bearing. However, if it is a regular ball type bearing something is not right.
