Re: 1958 Johnson 10 hp- worthy for resto?

[Bob Wight]

I have the same 1958 Johnson 10hp motor. Good advice from Frankr on the wrist pin issue – always a first good check. Assuming it passes that test, it could just be stuck rings or bad head gasket. Mine initially had about 80 psi in both cylinders. I soaked with some fogging oil and also found a bad head gasket. I now have about 95 psi and it runs great. Did all the other usual items – carb rebuild, new water pump, gear case reseal, all new gaskets. After I got it running I then did new paint and decals from NY Marine and it looks factory new again. The 1958 Johnsons had a great paint scheme and I would certainly say yours is worthy at least some effort to see if you can get it running.
