BassnChris Posted January 28, 2013 Posted January 28, 2013 Winterized 2001 Mercury 150 XR6 motor and boat by added stabil to fuel, fogged engine, then draining fuel tank, topped of oil tank and greased trailer bearings, tilt motor down and covered with cover and tarp and removed batteries. Sat outside 2 months then got it back in warm garage. Put batteries back in.....they have been kept charged. Today added startron in the amount indicated and went down and put in 10 gal of 100% gas....no ethanol. Got home and primed bulb , primed with key and started engine. Smoked like heck.....normal result from fogging. Got good stream of water and ran for about 2 minutes sputtered and died. Reprimed with key and fired up again......ran for 30-40 seconds with rpms running up and down by itself then died again. Could be starving for fuel but thinking it might be fouled plugs......will change them out tomorrow and see if that helps. Wondering......did I forget something before starting......did not seem like it? Quote
rdollar80 Posted January 28, 2013 Posted January 28, 2013 My boat did that (175 evinrude) and it was the computer. Quote
Al Wolbach Posted January 28, 2013 Posted January 28, 2013 About the only thing affected by winterization would be plugs. Not sure what type of gas tanks you have but make sure vent is open if portable..........................................Al Quote
BassnChris Posted January 28, 2013 Author Posted January 28, 2013 more likely than not fouled plugs This is what I was thinking. My boat did that (175 evinrude) and it was the computer. Bite Your tongue! About the only thing affected by winterization would be plugs. Not sure what type of gas tanks you have but make sure vent is open if portable..........................................Al not a portable tank...so that is not an issue. Plugs were all I could figure.........had the wife pick them up for me on Friday in anticipation. Quote

I hope that is the problem though.............Al Quote
Super User Nitrofreak Posted January 28, 2013 Super User Posted January 28, 2013 When you fog an engine it is recomended that you crank the engine without the plugs installed to get the access oil out of the cylinders, you have to disable the electronic ignition system first so you do not create an unwanted spark, chances are you just fouled a plug or two, either replace the plugs or you can burn them clean with a small propane torch and let them cool, if you install a hot plug it may ignite any fuel vapor in the cylinder so be careful. Most times once you run the engine under a load for a while or higher rpms it will clear out but it is not always the case especially if the ignition system is old and it has not been tuned for a while.

BassnChris Posted January 29, 2013 Author Posted January 29, 2013 Had wife buy new plugs last Friday .........just figured I needed to do that especially since I just bought the boat last year and do not know the history. Replaced the fuel filter today..........the longer opaque tube thing in this pic... Noticed I had hard priming bulb after just 1 or 2 squeezes and no fuel in the filter. Do I need to do something special after replacing the fuel filter? Disconnect the fuel build to sort of 'burp' it? And rdollar......I know.....just had to say it....;-) Quote
BKeith Posted January 29, 2013 Posted January 29, 2013 Any time you fog one for winter storage, it's recommend you take it to the lake, run it easy for a few minutes the get it warmed up, then run it WOT for about 10 - 15 minutes and change the plugs in it. Since you've already been running it, I would remove and clean the plugs, do not replace them right now, then wait until you can take it to the lake and run it, then put a new set in. Regardless if I fog one or not, if I store one for several months, I always run it once at the lake with fresh gas in it and then change the plugs. As for the filter, screw one of the bowl screws (main jet covers) out of the carb, should be a brass screw with a big head. Gas should drain out, then pump the primer bulb a few times and see if gas runs out as you pump the bulb. The filter could just have a big air pocket or there may be no fuel getting to it. Once you take the screw out of the carb and pump it, that will let you know. It should fill up with fuel with that brass screw out. If you can get to them with ease, take one out of each carb and pump it. That will make sure you don't have a needle stuck close from gummy gas left in them. If that all fails, pull a fuel line loose somewhere after the filter and pump it, see if you get gas then. If not, most likely you have a valve stuck in the fuel pump or gummy gas stopping things up.
