Hello iboats members,
I recently bought a 1981 Bass Tracker III that the owner put a Mercury outboard motor on, the serial number on the transom plate is 0A982085. Said it ran good and recently had some work performed on it.
All I can tell is that its an 80s(?) 3 cylinder motor and the cover says its a 50HP.
Previous owner had a new CDI Stator/Trigger installed on the motor. I bought the boat and the first time I took it out it ran badly and then eventually came out of it and ran great so I assumed it would be good to go. The next time I took it out it ran badly for 10 minutes and then ran good again until I shut it off for about 5 minutes then it ran poorly the rest of the time, just wouldnt go very fast like it had a missing cylinder.
When I pulled it out of the water I took it home and put a spark tester on it, it confirmed it had a miss on 1 cylinder, based on research I bought a CDI switch box and it fired right up running on all 3 cylinders and charging at about 13.4 volts. I took it out to test and it ran great again.. For a while... on the way back to the dock I was going at full throttle and all the sudden it just shut off like the kill switch had been activated.. Pulled the cover and now I have no spark on any cylinder with the new CDI switch box. When I brought it home I installed the old switchbox which used to have 2 good working cylinders and I still have no spark on any cylinder.
I disconnected the black/yellow wire at the switch box which is supposed to be the kill wire and I still have nothing. Now im worried that the motor has an underlying condtition that is ruining the ignition components, most likely why the previous owner had the stator/trigger replaced.
Ideas would be greatly appreciated!
Thanks
