Running Rough

Can a faulty ignition switch affect the performance of the engine while increasing the RPMs (in gear)
I have a 1993, 115 Yamaha 2 stroke. The issue I have:
When i turn the ignition key to the on position the rpm lights and fuel do not come on, runs fine at idle but when increasing to get on plane it bogs down. When the key is pushed a little further and all the lights are on, there isnt a problem. Does this sound like something that can happen from a faulty ignition switch?

well i have never seen it but yeh i guess it can happen and it sounds like your key switch is bad. do you know of anyone else with a yamaha you can hook up there control to your boat to check?
