SeaFoam's smoke galore.

Hey Gang!

After last night’s raccoon shift, it took me awhile to get going today. One very large coffee and I was ready to start my first winterizing task in a few years. I read Tin Man’s decarburization (is that a word?)  with SeaFoam, and decided to do it before putting the boat away. Got a small gas can with ¾ gallon of gas and mixed one can, (16 oz I think) of the stuff.

I did it in three stages and I tell you, after the first run that motor smoke its butt off.

(One of my neighbors drove to the cul-de-sac  to investigate the “new noise” and all the smoke)! I knew than I was doing GOOD.!!! ;D ;D




I repeated the process twice more, by the time I was done running that special mix, the motor not only ran smother but also ran at higher RPM’s.

Tomorrow I’ll change the lower unit gear oil and to satisfy my curiosity, I’ll measure the compression again before doing the fogging thingy, lastly is the frame for the tarp. Now... that’s gonna be depressing! :'( :'(
 
dont ya have to run your boat at WOT in the water after a decarb to blow it all out? or is that just for the spray stuff?

Yes...Dunk's method, the one I posted says so. It's the way I did mine. But maybe it's OK not to for winterization???
 
I didn't get a chance to do the s.f. on the mighty V, however I did it on my tin boat. I followed the "Dunks" method. It got pretty smokey,but less than I expected. After "blowing" it out, I noticed my rpm at idle was a touch higher than before. 35 H.P. 85 Evinrude, runs like a champ. :D
 
Those older johnnyrudes are bullet proof. The 9.9 kicker I got with my V-21 still runs like a sewing machine and its a 1975 model. Pull the hood and clean enough to eat off the block!
