I have a 96 Johnson 90hp outboard and I've done a few things to try and get it running happier at idle instead of dying. Before trying this I'd done Seafoam and other fuel treatments, and replaced the plugs and wires. Ran better but I still felt there was something lacking.
I bought this engine tuner on a whim based on the great reviews but I was skeptical, figuring it would be no different than Seafoam. Not so. Ran the whole can through the carb throats as the instructions state, which took about 15-20 minutes. Couldn't spray much at once since it would bog down the engine. Still wasn't sure there would be much change. Then allowed it to sit overnight and ran it again 15 minutes the next day as instructed.
Well, I'm giving it 5 stars. Engine runs smoother at idle and doesn't want to die on idle in the water like it used to. Well worth the money and I highly recommend it. I think it runs quieter now at all RPMs so the wife is happier too. I'll probably make this part of my annual maintenance going forward.
Just like seafoam but almost seems like it works better. Bought a new to me (used) motor and it was running a bit rough so sprayed a can through the motor and it runs and idles like brand new!
As always a great product. you spray this in your carburetor turned over a little bit without starting it. just so the system The product gets through the carberator system it will clean the carburetor. if it's full of dirt and debris you will probably have to clean the carburetor. but gum situations from letting it sit works phenomenal.
I had a discussion with an engineer that was on the design team at Evinrude in the 1980's. I had purchased a 1977 85HP Evinrude V4 and was talking to him about it. He told me it was a great engine and that the only real tuneup you needed was to run a can of this stuff through it. I ran the motor and sprayed the whole can into the intakes. Let it sit overnight. Changed the plugs. Started her right up the next morning she smoke white for a while and then after a good run purred like a kitten. No more sputters, just purrs. I'll be using this stuff every year to keep her running well.
Used full can on 1998 Johnson Ocean Runner 115hp 2 stoke. Sprayed in carb throats with engine running about 1200-1500 RPM. Let it sit over night and next day ran it at 2500 -3500 RPM for 15 minutes. Over the course of the 15 minutes it smoothed out the roughness significantly. I'll use this every year. Excellent stuff!
