"1989 Mariner 150hp problem wi
"1989 Mariner 150hp problem with losing spark. I recently bought the boat, and the prior owner told me of this problem. The boat had 2 batteries and 2 150 Mariner outboards. Port engine started and ran well. Starboard engine turned over weak. Thinking he had a weak battery he put battery switch from the "A" position to the "AB" position and tried to start engine. It fired a moment then died with no spark. He said the technician found a dead cell in the battery and that he also had lost his stator winding. Stator winding was replaced and ran ok. I come into picture and buy boat and on the sea trial (while still at the pier) the same engine turns over slowly and will not start as had happened before. He again thinks that engines battery is weak so he puts switch in "AB" position...it starts and runs rough for about 30 seconds then dies. Upon checking with spark tester, NO SPARK. Lost high voltage again. Have not checked to see if Stator is blown again,(didn't have ohm meter with me) but as for me, I CAN NOT SEE HOW A BAD OR WEAK BATTERY COULD HAVE ANYTHING TO DO WITH BURNING UP OR LOSING A STATOR . So now it sits waiting for me, the new owner to troubleshoot. There is no high voltage to any cyl of this engine. I plan to bring my tool box to the marina (100 miles away)and try to isolate what has failed to cause no spark. (Stator/trigger/voltage reg.rectifier, etc. The sellor of the boat spent over a $1,000 to get it fixed (stator burning up) and now the same thing seems to have happened. Can anything be wrong with the battery or A/B switches that could cause such a problem??? Any ideas on how to proceed ship mates???"
