![]() An improperly grounded switchbox will fail. IMPORTANT: Make sure you have properly fastened and grounded your switchboxes BEFORE attempting On the stator screws and flywheel nut as per your Service Manual's recomendation.Īlways re-torque all fasteners to factory specifications! Installation is the opposite of removal but make sure to use a drop of LocTite Lift off the old stator and label it with a marker as being "BAD". Remove all the wires from the switch box and the voltage rectifier or regulator/rectifier. Use the correct size allen wrench and remove all of the retainer screws. Most Mercury stators or held in place with 4 or more allen head screws. Once you have removed the flywheel you will see the stator. Order 91-849154T1 Flywheel Removal Tool below (see below for the Flywheel Holding Tool is needed). Most inline 4 cylinder and V6 Mercury Outboards require a special flwheel removal tool to remove your flywheel.Ĭheck your Service Manual to make sure exactly which tools(s) are required to remove your flywheel. Read your Service Manual for all safety precautions before working on your motor. ![]() IMPORTANT: Disconnect your engines batteries and spark plug wires BEFORE attempting to remove your flywheel.ĭamage, Injury or Death can result if the engine cranks or starts while you are near the flywheel. this might not be your only problem but you cannot procede with any moreĭiagnostics until you are sure you have a good stator. If any of your specifications are not within the recommended range, the stator is bad. Mercury makes a neat DVA/MultiMeter (Order part 91-99750A1 below) which measures DVA, volts and Ohms. To perform the Voltage Output Test you will need a special DVA Meter. To perform the Ohms Test you will need a good ohm meter. It is often the case that the old switchbox(s) fail shortly after a new stator has been installed. This is because a bad stator can weaken or ruin a good switchbox. Mercury Marine recommends that the switchbox(s) be replaced in the event of a stator failure. Keep in mind that a bad stator might not be your only problem.Ī bad stator can cause a switchbox to fail. If a stator fails the Ohms Test, it is bad. Just because a stator passes the "Ohms Test" does not mean it is good. Some failures only show up clearly after the motor has reached operating temperature.Īlso. In general, there are two types of tests.īe aware that stators can give different results depending if they are hot, warm or cold. Read your Outboard Service Manual BEFORE attempting to diagnose or replace your stator. ![]() The procedure for performing an accurate diagnosis on your stator will depend on Bad batteries, bad battery cables, poor connections and wrong style of batteries can cause the stator to get too hot from attempting to charge the batteries. An engine that is running too hot will "overheat" the stator.ģ. Age! Old stators fail from internal failures from temperature fluctuations and/or corrosion.Ģ. Stators can fail for one or more of the following reasons.ġ. Vessel's battery(s) keep going dead or have too low of voltage. Engine does not recharge the vessel's battery(s).Ħ. Engine is low on power or has a "miss".ĥ. ![]() ![]() Engine is hard to start especially after sitting from a run.ģ. They provide voltage to your switchbox or CDM's.Ī faulty or failing stator can cause one or more symptoms.Ģ. Most Mercury Outboard Stators perform two important functionsġ. Your outboard stator is the "powerhouse" of your outboards ignition system. Mercury Outboard Stators Mercury Outboard Stators ![]()
