No spark on a 50hp Mercury Force outboard

[pappydear07]

We have a 50hp 1985 mercury force outboard that has no spark. We have replaced the points, condencers, coils, plugs and plug wires still with no spark. We are at a loss as far as what else it could be. the motor turns over when you turn the key. We just dont have any spark. Does anyone have any other suggestions that we could try.

Test the rectifier, you will need a DVM (Digital Volt/Ohm Meter) and a manual for the proper trouble shooting/testing sequence and voltage readings. Most likely the problem is ignition circuit.
