Make sure your engine is producing electricity and battery is good (this does not mean charged you must have it load tested). If both of these are good than you might have a weak trim pump or a bad valve body. You can get these parts aftermarket through sierra.

Answer: Every Mercury outboard has a serial number label located on the transom bracket area of the engine. The latest serial number labels display a 2-digit number in a box at the lower right portion of the label. These digits coincide with the last two digits of the year in which the outboard was manufactured.

Does it turn over? But won't start? Have you checked the spark? My thought, if it turns over it's not a fuse. See if you have a spark at the plugs, YouTube will show you how. If spark! Next is fuel. If no spark, Probably blown ignition module, not fuse.

That serial number was produced during the years of 1988 through 1990.

Take out the spark plug. Hold a drinking straw up to the spray nozzle and shoot the fog into the spark plug hole.

Best not to do it as you will get maybe 2 mph. Also, I believe it is ******* to modify 1996 and later motors.

If you know the year or model number, you should be able to find the diagrams at http://www.crowleymarine.com. Otherwise call, I've known them to be really helpful.

Any outboard 2 cycle after 1965 will run on 50:1 approx 500ml or half a quart per 5 gallon tank.

(Carburetor Adjustment - Single S/S Adjustable Needle Valve) Initial setting is: Slow speed = seat gently, then open 1-1/2 turns. Start engine and set the rpms to where it just stays running. In segments of 1/8 turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back (sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting. Note: As a final double check setting of the slow speed valve(s), if the engine has more than one carburetor, do not attempt to gradually adjust all of the valves/carburetors at the same time. Do one at a time until you hit the above response (die out or spit back), then go on to the next valve/carburetor. It may be necessary to back out "all" of the slow speed adjustable needle valves 1/8 turn before doing this final adjustment due to the fact that one of the valves might be initially set ever so slightly lean.

Sounds like the gas isn't flowing freely into the carb. Check to see if the gas lines are open, no obstructions. Also check the gas tank, I there is a screen on the gas inlet tube and that might be plugged.

There are some universal ones available, but I just stick my 9hp outboard in a bucket of water and flush that way.
