Gentlemen,
How many RPM's should a 200 mercury turn? I'm no mechanic by no means but surely an outboard motor on a high performance boat will turn at lease 5500 easy. Here's the deal, I took my motor to a local "out of his house" mechanic because my motor at WOT would only turn 4000 RPM's with a 25p tempest plus. He tells me I have good spark and compression on all cylinders but that the pitch is too big for this motor and that I need a 23pitch. I listen to him since he is the machanic and get a 23 pitch. Now I only turn 4500 RPM's. I tell him it still wont turn any more than 4500 so he says, bring it back and I'll work on it. One week later he changes out the throttle postioning sensor, 2 injectors, and installs a idle stabalizer. He then tells me 4500 is the best this motor will do and that nothing is wrong with it, oh and that I now owe him 791$. WHAT!!!!!! The motor runs exactly how it ran when I took it to him the first place. I know I need a new mechanic, but what RPM's should I be running and what else could it be? Its a 1991 mercury 2.4 200 Electronic fuel injected on a 19 ft norris craft. The boat will only go 50 with this motor on it. Norris craft tells me the boat was made to go 70 + with a 200 merc. Help please.........
