Re: Help Please I am out of Ideas

Have you looked at the stator physically, wires ok? Cracks in insulation? Ground wire connected (if the type with a separate ground). Ground wires on switch box mounting screws?

No I have not physically looked at the stator, the wires are not in best of condition, but this will be something that I look at

I believe that the orange wire to the switchbox is the kill wire that turns it off when you turn the key off. It provides ground to the wire in the off position.

So, one switchbox does not provide spark, and the other gives you spark but will not run. I've heard that these boxes can go bad by drastically changing the timing. It could be that the new used one is also bad.

Thank you for the what the orange wire is, I will cross reference it with the newer switch box.
The motor that they(switch boxes) was running when it was pulled, it had a blown power head. But I will check with the second box that is on the other motor.

If you got spark when you swapped your
switch box but now it's popping,could be
the switch box but first I'd double check
all the wires on the switch box and coils,
maybe a couple wires are crossed?

I had a old merc that would do the same thing. Only it had about half power when cold and first start. I found the motor was flooding, over choking when I was starting it. After letting it set it would run good. maybe you have tomuch gas in the crank case when it sets, or your over choking at restart.

I went back and double checked the wiring, everything seems to be wired correctly. I did notice that one of the wires from the trigger has some bad insulation, after pulling back the insulation I noticed that the wire is corroded pretty badly. Does anyone have any experience with a bad trigger? what are the symptoms?

Re: Help Please I am out of Ideas

This is exactly what is happening to my 1976 OMC straight six. It runs like a new motor out o fthe marina. RPM's are great and moves fast on the water. I can have 4 people in the boat and drive around for a while. Then... I stop the motor and just chill or fish on the water and when I go to start it up it moves very slow can't get up on plane, battery charge seems to drop, struggle sto even make it back to marina.

Coil?

Re: Help Please I am out of Ideas

Ok I will up date this tread. I finally got the motor running in early winter last year. After switching back and forth on the coil packs I found that I had two bad packs out of 4. So when I had originally swapped the coils around I had gotten a second bad one. Go figure.

Now here we are, almost a year later, and the motor and boat will run faster than I want hold it at. lol
