This is a '95 F50 that was running great last weekend but this weekend started acting up. It starts great, idles great but when you throttle up to about 2000 RPM, it starts to miss terribly. If you throttle up into the higher RPM range (maybe around 4000 or so) It levels

make sure alarm system works, could be the motor has a problem and it is not letting you know what the problem is or that it has a problem

I'm not sure how to troubleshoot the alarm on this boat. I do know it beeps when you turn the switch on. That's about it. This boat belongs to some friends of mine.
