Problems with a Force 40 HP?

Question

A friend of mine has a 97 model 40 HP Force outboard that has a problem. There is no fire to the bottom spark plug.

We took the coil off the top and put on the bottom, no fire. Replaced the wiring harness, no fire. Replaced a small electronic box just above the solenoid and still no fire. About the only thing we haven't changed is the stator beneath the flywheel.

Question is could that be where the problem is? The upper plug fires and the engine runs just on the one cylinder but runs somewhat rough.

Any and all suggestions greatly appreciated.

Answer 1

could be the trigger, which is far cheaper than the stator.  you really need a manual because if i remember right, that engine has a "red" stator and CDM's.  very complicated system.  a bad coil can stop the other one from firing.

Answer 2

I work for a boat dealership, and they tell me "Force's are harder to get rid of then Cancer". I know thats absolutely no help, sorry. :)

Have you had a mechanic take a look? Sometime a second opinion helps.( we do check-outs for about $70) You can do the repairs your self and save money, but you won't have to play guess and check. Good luck.
