hi..i have a 1996 force 40 hp on a 16 ft pontoon boat and yesterday was my first day out on it. When i got it we put a new impeller on it and put some muffs on it and it fired right up. The guy i got it from said it had been sitting for 2 years because the water pump stop pumping in the water with him and it got hot so he cut it off and had to get pulled in.so i let the motor run for a while with the muffs on and it ran good..idled good...and whatnot..i dont know a whole lot about boat motors because i put, i think a 11p prop instead of a 10 p one..and it didnt want to run in its power band..of course..i burned a 6 gallon tank of gas in no time...i went in after about a hour cruise to pick up someone and we changed the plugs, to try to help it out..and there was like a little of milky stuff coming out to the bottom spark plug hole..we put the plug in and fired it up...it ran fine..so we took it out for some more testing..when the tank got less than 1/4 empty we went in...and then it started smoking ..pretty bad..and really didnt want to keep an idle..i havent had a chance to talk to any one at my local boat marina...but i figured that someone here would know something about what i might have messed up..and by the way i mixed the fuel about 45 to 1...if anyone could help i would appreciate it...thanks..
