Seafoaming my Johnson - advice?
Posted on 6/19/13 at 8:46 am
Posted on 6/19/13 at 8:46 am
My Johnson is damn near 20 years old now, it mostly runs like a top but it's little rough in the beginning at idle, and lately when I try to get it up on plane it sometimes bogs down slightly for a few seconds before it gets up and going.
I want to try seafoaming it first. Do I just get a can and follow instructions on it, or is there some better way to apply the seafoam to my Johnson?
Motor is a 94 Johnson 48 Special
TIA

When was the last time a mechanic looked at it? My dad had a Johnson years ago that started that, but it would "run fine" after that. Until dropped a cylinder....
You may not have that problem, but I'd have it checked out. Does it kind of bog down and surge?

Try shaking your Johnson there may be junk stuck in it

just seafoam the tip of the johnson, just for a sec, just to see what he does.

I knew this wouldn't end well

Yes, it's a good idea to add a can of seafoam to a full tank of gas to keep carbon down, but if you also wanna use it on your Johnson...well that's your business!

Agree with the advise you are getting but did you change plugs and are you using good gas and or treated gas in good fuel lines?
3 things to look at there.

Have an evenrude doing the same thing. Let us know if you figure it out. It has been to the shop several times with no good results. You cant tell by running it on a hose. Even on the water it is hit and miss for acting up.
I have sprayed power tune in it years ago when I had a carbon build up problem and it did wonders. Maybe we need to try that.
