I have a 2002 225hp optimax outboard ,I have no ignition at motor no power ,its not a fuse and its not the battery ,and it has a new data cable ,everything is brand new

many mercury motors use a rubber mounted prop on the shaft which is a sacrificial idea to prevent gear box damage and prop damage in with under water objects
what you suggests indicates that at certain load situations that rubber has failed and allowing the shaft to turn but is not driving the prop as required
It is driving just enough to give you steerage to get home

Follow engine harness. Do you have positive and negative voltage on starter?

Bypass solenoid,put jumper from pos on batt to starter motor,but could be so many things,faulty battery cables,broken wire in loom,worn starter brushes,faulty solenoid ,start in gear switch or ignition switch

buy a new one from Quicksilver dealer or a breaker !

Red wire w/purple tracer is 12 volt (+) supply to ignition switch. Purple wire is switched 12 volts that supplies 12 volts (+) to the circuits that are turned on by the ignition switch. If they are getting hot something in one of those circuits is drawing excessive power. This should cause the engine fuse to open the circuit to protect any damage. These early direct injected engines are very sensitive to voltage deficiencies. I would begin with the battery: make sure it has sufficient cranking amps, more is better. 800 - 1000 Cold Cranking Amps is a little more than minimum spec but that is what I would recommend. Make sure the battery connections are clean and secure, NO WING NUTS! Battery connections should be secured with an external tooth lock washer at the bottom of the stud followed by the engine cable so the washer bites into the lead and the cable lug. The cables should be marine quality tinned copper with a secure connection to a tinned copper lug. The cable must be sufficient size for the distance run. These engines and the electronics they are equipped with require good clean 12 volts. They can sound like they are cranking fast enough, like the battery is strong enough and not have enough to power the ECU/EMM and injectors. The major benefit of the newer E-Tecs over these early Direct Injected and Ficht outboards is the stator output and its ability to power the electronics without the dependency on the battery. The battery cranks the engine and the more advanced stator and flywheel magnets supply the voltage for the electronics.


Hope this helps. Make sure the correct fuse is installed in this engine. There are multiple fuses in the power distribution panel on the starboard side of the engine. They are all 10 amp ATM fuses.

Start simple, check all fuses. Check voltage at power supply.

if you mean the cowl below the top hood then there are bolts front and rear and poss a couple of clips inside then pulls off !

Jaysen,
Weren't the plug wires made into the ignition coils and spark plug caps?
..This sounds more like a fuel delivery issue than electrical... have you changed the fuel filter?.. does the fuel line bulb stay pumped TIGHT!!?

you do have new spark plugs!!
