1994 mercury 135 no power

Recommended Posts

Just wanted to put this out there, maybe someone else has had this problem.


I had my motor lockup a while back, so I took the foot off a week later and it cranked up, sent the foot to a mechanic and he stated that the inside of the foot looks brand new, so it was not the foot.  Put the foot back on, and it ran! AWESOME!! Took the boat to Lake Greenwood and ran it WOT for about 5 min and it locked up again. SHOOT!! So since I couldn't go anywhere I fished for about 30 min, and tried the motor and It cranked right up, but now I have no power to get on plane, the motor would not get over 3000 rpm's.  So now I took the whole boat to a mechanic and he notices a brown spot on the power head.  What that is from, is water that is suppose to be cooling the engine is leaking out of the head gasket.  So the reason I could not get the power to get on plain is because one of my cylinders was getting water in it and was causing the cylinder not to spark.  


Hopefully I caught it in time and did not ruin a cylinder.  

Hope this helped anyone that might be having some issues as well.
