    just got a boat and it has a early 70's johnson 9.5 hp. ran good for a couple of days but recently when giving it gas seems like something is slipping at times, kind of like a transmission in car. lower unit maybe? If it gets worse is it worth fixing?

    Are you saying that the RPM's will come up but the boat slows down in forward movement. Or is it jumping out of gear.
    Give me a little more info here.

    Could be the rubber hub inside your prop has deteriated or separated. Had a 75 HP do that once. Run like a son-of-a-gun, but you could walk faster. I'd definetley check the prop first.

    Get your prop rehubbed. That's all it is. Like the other guys would tell you. Or get another prop.

    In this area, and depending upon which shop you go to, it would run between $40.00 to $75.00 to get the prop fixed. You may find one the same size on ebay cheaper - don't forget to check the handling and shipping if you look at ebay.
