Need help a.s.a.p

[Saskatoon2005]

Hello all and thank-you in advance for your help...<br /><br /> I am having trouble with my 1978 Mercury Outboard. It is a 7.5 H.P. I took off the carbueretor and took it apart and cleaned it right out. I changed the gas, put brand new gas in it and finally after what seemed like forever...it started. The motor had to run with the choke pulled out half way.<br /><br /> Here is the problem. I turned off the motor for about two hours, and when I tried to start it again I could not get it going. I am using the original 1978 gas tank, you know, the one that is completely made of steel. I could only get the motor started in a pail of water and I had to have it in gear. The motor only ran for a couple of seconds and then quit. I could not get it started in the neutral position. I was wondering if the old gas tank could have impurities getting into the fuel and then corrupting the gas flow. Please help me as I thought it was running perfect and had planned to use it tomorrow but now I can not get it to run at all. Once again Tank-you in advance for your help.

Get A 6 gallon tank at walmart and fuel hose.<br />Give it A try. You may have to clean carbs again!<br />Also you may want to add A inline filter.

I hope you are not speaking of the glass type....<br />I hear that the cannister filter /water seperators do more and work better at filtering trash and help with any water that can accumulate in a tank.

Another person had figured that I was running on one cylinder, could that be true, and if it is, how do I check for this? I did check the spark on both plugs and both were equally strong. If I put the motor into gear and increase throttle, then sometimes I get the motor to start, but unfortuenately it won't stay running.

I have been told that the motor requires a new stator, of course a part they no longer make anymore. I guess I will have to replace the coils on it and see how that works then....I will keep you all up to date then.

If it ran ok for a short while, chances are it's probobly a fuel problem...not electrical. If<br />you want to check to see if it's running on one cylinder, pull a plug wire off while it's running and see if it changes.
