i have just recently bought an 89 bayliner capri with the 85 hp force motor with L-drive. I rebuilt the starter and got it to turn over, after not starting i checked the plugs for spark, only the middle cylinder is getting spark and the top and bottom arent(3cylinder). I traced the problem back to the cd boxes, there are two(blue). I switched the leads from the middle plug to the top and bottom and found by doing this they will both have spark but only one at a time. Do you think that it is the cd box or possibly a stator problem? how can i test it? Also what exactly does a CD box do? since the one plug is getting spark can i run leader wires off the good wire to the other two coils or is there a timing issue involved. Any help is appreciated. thanks
