Reply To: 1973 9.5 Hp Evinrude

[JACQUES]

I have fixed up half a dozen and all had weak compression compared to other motors mid 60,s PSI is ok by me and you will find leroy’s article highlighted that very same characteristic

do the electricals .. (coils) adjust the cam follower , adjust the carb, inspect -change impeller & gear oil and go for a good ride. my 9622a run perfectly at 65 psi

“A normal compression reading of 65# to 75# appears to be fine for this motor.”

utube has good videos on carb clean up of the 9.5hp

if you can wait a bit chineese coils are ok and cheaper . I have had no issues with them
