I have a 1982 model Mariner 30hp outboard and the guy that I bought it from had to get the lower unit changed out at some point in the motors life. I bought an impeller and a seal kit for the motor off of this website and it wasn't quite right. It was close but some of the seals looked a little off. So now I have to figure out what the foot came off of. Is there any way to do that? Thanks.
