Reply To: 1975 Johnson 6hp powerhead

Gentleman,

Apprecaite all the help. I bought a 1970 6hp fisherman pwr head off a guy 3 hours south of me. Looks to be in good shape.

I verified that my ignition will work with it. Has all the same part numbers. Will get it mounted this week sometime.

Next question.

Is it worth it to rehone the cyclinder bore and drop new pistons in the old pwr head.

Pistons are $40-$60 with or without rings and hard to find.

If i have to bore it, i have the tools in my shop to bore it .010-.030 over. I saw there is a kit on amazon with rings, piston for .020 for $60. Then i would have to get pwr head gasket set $55 & headgasket $30.

So total rebuilt would be about $220.

Would it be worth it or just buy used pwr heads if compression is lost?
