Your probably running on one cylinder. The motor will start and run just fine, but wont go very fast on one cylinder. Pull your plugs and find out if both are firing. Check the spark, it should jump at least 5/16 inch with a blue arc. Let us know what you find.

Put the dadgum thing back together and find out which cylinder is not firing. Then troubleshoot from there to find out why it isn't firing.

You find out which is not firing by pulling one plug wire at a time to see which one has no effect when pulled. Hint: Don't pull the wires with your bare hands while running. Pull one while not running and ground it, then start the motor and see the results.

Hey, it could be as simple as a bad spark plug, or as bad as a blown piston. You have to troubleshoot it from where you are.

OK, so you have proved that it is running on both cylinders. Now all that is left for us to do from a distance is guess. You are there at the boat, so it is up to you to figure it out. Is something wrong with the boat, like marine growth on the bottom? Are you hauling around 50 gallons of water under the floor? Is the propeller hub slipping? Motor tilt way off? Tied to the dock? Sorry, I couldn't help that last one.

Good luck

With the motor off.
Put motor in gear, advance throttle to wide open throttle. Check the butterfly on the carb. It should be wide open. Also check to make sure the neutral safety switch rod is not engaging the spark advance plate. If that all checks out, make sure your motor isn't overheating. It should have a good tell tale stream of water, and the head temperature should be around 145 degrees. If the motor is overheating, a sensor puts the motor into "slow mode" and will not go over 2000 rpm.

On the left transom mount clamp there should be a motor identification sticker. The number will tell what year your motor is, and I would recommend getting a OMC service manual for your motor. Used manuals can be found on ebay at about half price a new one. This manual will help you greatly in knowing and repairing your motor. OMC is the best manual, the "other" manuals are just about worthless, and a total waste of money.

Your year model went to the CD2 ignition, which included the sensor coil in the powerpack and both are under the flywheel. I'd suggest you get an induction <clamp on type> timing light and test each plug wire while running wot on the lake. This might take 2 people to be on the safe side.OMC only utilized this CD2 ignition from 89-92 <from what I can tell> then went back to separate sensor coil/powerpack..with the powerpack no longer under the flywheel.

Cofe brings up a good point. Perhaps it is going into S.L.O.W. mode. Something I know exists, but am not familiar with.

Before tearing into it too bad, I say check your prop good, weight your boat to make sure you dont have a bunch of waterlogged foam hidden in there (bass trackers are known for this) and then make sure its hitting WOT
