Hey guys I have a 1967 mercury 9.8. The bottom unit oil leaks out around the prop so I'm sure my prop shaft seal is shot. I looked behind the prop and it looks like I'd also need to replace the bearing and I'm sure several other things too. I just spent $65 getting new fuel lines for this boat and for how old the motor is I'm really not willing to put much more money into it. I probably just keep filling it with gear lube hopefully it'll last at least a week at a time? So my question is, is there any cheap type of oil you can use to fill the lower unit with? Also what's the easiest and fastest way to fill it? Take the motor off the boat?
