PCM 351 Trouble

I have a 1985 Ski Nautique and I have run into some interesting issues. The first time I took it out on the water, it ran fine for a little bit then bogged down and began to skip at higher rpms then quit. I could not get it back started after that. Once in the shop, we realized the electronic ignition module went out so we replaced it and it cranked right up. I took it out again and it ran great for about 15 minutes then had the same problem. Once the engine cooled it cranked right back up so I could get it to the ramp (almost to the ramp; it died again once the engine heated back up).

I called a knowledgeable person on the matter and he said to move all wires on the resistor block (coming from coil and distributor) to the right (positive) side. It cranked right up and I idled around for about ten minutes with no issues and the engine ran great at high rpms when out of gear, which it did not do when the problems were occurring.

Question: Will keeping those wires on one side of the resistor block cause any major issues? Also, why did that fix it?

All of the wires from the coil have been run to the resistor and I believe are set on the 12 volt side now. It is the electronic conversion.

Sounds like fuel starvation is also occuring - crap in the antisiphon valve- (within the tank outlet's hose barb) and/or cone screen in the tank's dip tube assembly.

As been said, all sorts of igniters are out there all have different setups and wiring conditions depending upon the coil resistance. Hopefully you still have the instructions.

The different methods of connecting electronic ignition modules was discussed in length in a previous post. Dig through it and you will probably find the instructions for the unit installed in your boat.
