Re: need help with my jet boat!

Please post up the engine serial number and if you have a CDM or CDI ignition system. Also post the HP of the motor. Do you have an OHM meter to perform some tests ? Please check your stator wires and see if they are blue and red or green/white and white/green.

hi the engine number is OE 114853 i checked the resistance from the starter from the blue and red wire and the blue/white red/white and there was no reading. i think its the cdm ignition but im not sure how to check

I looked and you should have a CDI system with a switchbox. Start with these 4 steps

1. disconnect black/yellow wire at switchbox and see if you have spark.
2. disconnect yellow wires going to the regulator , recheck spark.
3. Ohm Stator as follows , Red to ground , Blue to ground , post readings
4. Ohm trigger , Use white/black for one lead and check the other 3 wires separately. (purple , white and brown )

Also be aware that you should never run this boat out of the water unless you have the dealer type flush kit hooked up , You can and will blow the ride plate off !!

PS a CDI system runs a switchbox mounted on the same engine bracket as the coils. stator and trigger wires will run to this box
CDM will not have a switchbox , Trigger and stator wires will run to connectors then straight to the cdm's
