200HP Mariner Problem
My 1994 Mariner 200 FI started running a little rough Saturday. Nothing
major, but then my last motor started out as nothing major too, and I still haven't got it running right. The first symptom I noticed was the tach wasn't working. I still seemed to have plenty of hols shot, but that motor is way under propped so it would take a pretty bad problem to be really noticable. When I went over another boat's wake and smaicked against the water the tach started working again. I felt under the dash to see if it was a loose wire and if wiggling the wires would duplicate the problem, but it did not. Another time I noticed the tach out I cut throttle and then brought it back up again and the tach started working. Shortly after that I started to notice a miss. I would be cruising at around 50 in the 5000RPM range and it would have a slight loss of power like a cylinder quit firing and then start back up again. What would you suggest? Fouled plugs? Bad Pack? Bad Coil? This engine has run fantastic everytime out until saturday. When I finished up for the day and idled into the harbor it seemed to be idling a little rougher than normal. Also, it seemed to be blowing more smoke than normal when I first started out in the morning. I figured that was just from the 5:30am start and it being a little cooler than usual at about 52F outside. -- Bob La Londe Yuma, Az http://www.YumaBassMan.com Promote Your Fishing, Boating, or Guide Site for Free Simply add it to our index page.
