mercman i put a new stater, two cd mod.,trigger and 3 coil packs on this motor then i hooked up my water and started the motor up. the 3 cyclinders were all firing in order. giving the moter thottle it responded perfect. then we loaded her up and headed to the lake [alum creek].docking east of the beach ,i ran the boat north to state rt 36. i then turned around and drove it south to the beach. aprox. 30 to 45 mins. i then shut the boat off. every thing seem to be just fine. after swiming for a couple of hours i started the boat up idle was fine,droped it in gear. when we reached the nowake boowie i gave it more throttle and it droped on it's face, i pulled the plug wires to fined no spark in no. 2 and no. 3 cylinder. after taking the boat home i found my cd mod.have no electrical power. i think that explans why the plugs are not firing and causing 2 of the three cylinders to flood out. something is causing an electrical malfuntion. if i was to go out and buy two more cd mods. i can regain fire in all cylinders again. but after runing the moter again [same problem]. please help thanks
