96 force 120 no start have spark and fuel????

[Frankinbarnes]

Ok took my mako out to the reef today and left my girlfriend to start the motor and tow myself and some friends around... she flooded the motor or so i think... and then i burned out the starter trying to get it to crank right after that. towed the boat back home.. found a used starter put it on changed the plugs.... still no fire.. checked spark have it at all 4 cylinders... compression seems good... have gas in the inline filter right before the carbs... wtf???? boat ran great all the way out 10 miles yesterday and today no problems.. i dont get it. could it still be flooded... i pulled the plugs and ran the motor over for a good 30 seconds. could it be some kind of ignition advance problem?

Are you putting the power lever in the start position and using the choke?

hey john thanks for the reply! i do have the lever in the start position and i have tried the primer switch... now i just found that the 4th plug is not producing spark.. im also not impressed with the quality of spark i am getting from the rest of the plugs... i switched the coil wires on the cdi box and got the 4th plug to start sparking and the third plug to stop so its not a coil pack... should i order a cdi box or should i look elsewhere? please help i am in a pinch only 4 days of vacation left and no boat!!!! thanks ryan

CDI modules are not cheap so I would do some additional troubleshooting before buying one.

The first thing to do is clean all the grounds and any connectors in the stator/trigger/CDI module/coil circuits. If you have a manual, ohm out the CDI module and see if it is in spec. If not, then it is probably toast.
