    Water Pump Housing Not Machined... This is hard to believe.

    A friend gave me his 1965 Johnson, 9.5, MQ 11. Says he's tired of dealing with it. Can't figure out what's wrong. He put it up several years. No other information other than it is junk to him. Every subsystem on this thing needs help. I gave it new condensers, spark plugs, head gasket...
