Hi, hoping someone might be able to help me out, bought a 1989 Champion bass boat, that had been repowered with this 1986 DT200 motor three years ago, had been sitting for three years, I have been restoring the bass boat it came with and have in the process, completely removed the plastic fuel cell, and washed it out with K100, replaced all of the fuel lines and vent hoses and fill fittings, rebuilt both fuel pumps, and all three carburetors, by a professional, first run with new 93 octane, no additives, the boat fires right up, and idles fine, as you engage the motor, boat runs fine up to about 1500 rpms, and then the motor will stall, or sputter out, and I can play with the throttle, slowly, and sometimes, it will take off, like nothing and run fine, until i shut it off again. It will stall out 100 times more than it will take off and run fine, it sort of sputters through that 1300 - 2000 rpm range and then, will smooth out and run great and with plenty of power. This is a real nice freshwater motor, parts and mechanics that will look at this thing are hard to find, I have the manual and have most of the tools, have owned boats and maintained and worked on other brands of motors, boat is equipped with the smart gauge, and first run the alarm was also going off. noticed the smart gauge wasn't reading at all, so got home, found a power wire off the gray from the ignition, went out to the lake again, no alarms now, gauge powers up, correctly, and stays green, but the motor still sputters out, 90% of the time i put in in gear. should I start testing coils or CDI unit? Stator? not sure where to turn next, any help would be greatly appreciated
