Re: Mercury Sportjet 120, No Spark, Help
I just traded off my 95 SeaRay with a sport-jet 120. Had it for three years and had your problem and it was the electronics/computer module. <br /><br />The things are notorious for hard to start problems, I wore a battery out the first time I took it to the lake. When I got back with the new battery a guy was wiping down the same type of boat. And when it still wouldn't start he came over with something in his hand, and said "you haven't had this boat very long have you." I said I just got it, he had a can of Gunk Carberator Cleaner, there are two little access ports, one in front of each carb. He popped off the upper one and gave it a 1-2 second spray right down one of the carbs. It started right up and I always used it after that if it sat even over night and never had problems again. <br /><br />When the stator went out a year or so later that took care of the problem for ever. I heard there is a stator upgrade for them and I must have received it<br />. Because I barely even hear the starter and the thing is running. <br /><br />Good luck.<br />Hey lonewolf send me a copy to my email, please<br /><br />Cap'n Steve
