My 1984 75 horse 4 cylinder merc is giving me a serious headache.
For a few weeks now it is going back and forth between being a great machine and then refusing to start 2 hours later.
I drained the fuel tank and only use fresh seafoam laced fuel.The carbs are very thoroughly gone through and the fuel hose is brand new.The fuel pickup is clean.Last year I put in a new stator.
Today I ran about 8 miles and it started right up and ran like a champ.Half an hour later,it refused to start,but this time my nephew was with me and I asked him to start the engine while I checked for spark.There was no spark.So by now we eliminated fuel supply and discovered that there is no spark,although I suspect that tomorrow the engine will start up like nothing ever happened.
Is there a prime suspect for this sort of engine behavior?
Salmon season is starting to heat up and it is no fun limping back on a 9.5 little rudy kicker,even though it is currently more trustworthy than my 75 horse merc.
As always,thank you for your answers to this thread.
