Re: 76 Mercury 1150 water pump drive bearing shims??
well this was a dee dee dee question on my part. i assumed it needed more shims because i could barely turn the driveshaft after i installed the new water pump and i assumed it was hitting the bearing. then i remembered that the new impeller is a tight fit until it loosens up.
