So our motor in our boat is acting very odd. We took it out on the river and it ran totally fine! But the next time we went out it started acting up it was only giving about 20% throttle. So we loaded it back up took it home discovered that the bolt on the forward/neutral/reverse leaver was loose which he figured it wasnt letting the motor fully engage into forward, got it tightened up and looked and didnt see anything else. Ran it in a barrel and it was running like a champ! Took it back out on the river and it was still only giving 20%. We leave the motor unlocked just incase we hit a snag. Any suggestions?????:confused:

Welcome to the forum.
Have you checked spark and compression to make sure both cylinders are firing?

Re: HELP! Johnson 20hp

sounds as if you are running on just one cylinder getting spark,
