[QUOTE="Lil' Blue Rude, post: 390655, member: 4627"] One way to rule out if your loosing fire on the #2 cylinder is to hook a timing light to it. Leave the boat hooked to the trailer and trim the motor up some and have someone give it gas while you watch to see if the timing light starts missing or not. That should let you know whether it's in the carb or do to electronics. Had a guy a few weeks ago thinking he had fuel pump problems checked it with the light and turned out to be bad power pack. Not sure how well this would work on a prop motor but it works for jets. I just barely back the boat far enough in the water to get the shoe in the water, that way most of the boat is still resting on the trailer. [/QUOTE]
