1988 48 hp impeller housing leaking water through top drive shaft opening? is this normal? Motor does not over heat and has a good pee stream. When hooked up to muffs and running water trickles out between the lower unit and mid section seam so I removed lower unit and installed muffs and squeezed the muffs water came out drive shaft opening. I ma not sure if I need to do anything? tnx in advance
