Pulled # 5 main cap and found lower half of shell was missing babbit and copper. Top of bearing shell is in good shape, Crank looks good. Mains on either side of 5 look like new. What could cause half of a bearing to flake?
I am doing everything I can not to have to remove this block and crank from the boat.
