I have a 95' Sea Rayder F14 Mercruiser Sport Jet 120HP Jet Boat that WON'T START. I am getting fuel to both carbs, brand new spark plug wires and plugs, 150 compression in all 4 cylinders, will turn over strong but will not start.
The ground wires to the coil packs looked really dirty, so I replaced all the wires and made sure it was grounded to bare metal surface. I thought for sure that would fix it.
On the switchbox assembly, all of the wires on coming in from the stator have power when you bump the ignition, but all of the wires going to the coil packs do not light up when the ignition is bumped. The spark plugs are getting spark I do not believe enough to start the motor. I don't get it, all of the power wire and ground wire terminals to the coil packs are brand new. All of the magnets and coils looked good too which leads me to believe that it is the switchbox. I have checked every fuse 50 times, disconnected the black/yellow kill wire to the switchbox and still nothing.
I have attached the ignition schematics with the parts list.
PLEASE HELP, PLEASE! Thank you in advance.
