For sale is the powerhead for 1977 OMC Johnson Evinrude 9.9-15 hp outboards, this may fit other models too. This powerhead is in good working condition, it was removed from a running outboard that was only used in freshwater. Compression is good- both cylinders had 110 PSI when we tested it. The reciprocating assembly is nice and tight. This is a good replacement powerhead. See pics. 

If you have any questions, please ask! 

This part was removed from a 1977 Johnson 15 hp outboard with the model number: 15R77M
