My Bayliner is not running well and running after I shut it off. I have bought some Seafoam and would like to know the best way to run it through the system ie. fuel tank or put it in the crank case or through the carb. Thanks!!
Sea foam works really well in outboards.I dont think you will see any difference in an i/o.I would use it in both the fuel and oil and a decarb treatment.Charlie
SeaFoam is good stuff but it will not solve a "runability" problem that is mechanical or electrical in nature. If carbon or fuel system varnish and crud are the problem, chances are it will help.
