What is the compression for a 1974 Johnson 65 hp outboard?
In the early 1970's, when you could still get good gasoline, outboard compression in the 180-190 psi range was common. If your 65 hp Johnson is running in the 100-150 psi range, this would be acceptable, and the engine should still perform well on todays fuel. The important thing to note with compression readings however, is that the difference between the highest and lowest reading, is no more than 15 psi. One more note, avoid fuels containing alcohol if at all possible.l
