ive got a 1986 or 1987 25 xd mercury that has a mid-range power problem. it starts right up and idles great. and when i give it full throttle it screams (nice, lots of power) but anywhere between idle and full throttle it doesnt rev up (until i get to full throttle then its great). anyone have any ideas? i just replaced the flywheel with one off a similar 18hp motor. and the cdi box off a differnt motor ive tried adjusting the timing but no luck. ???? clogged jet maybe?
