I need help on my 242 limited s jet boat which there is no spark on the port engine swaped computer box, fuse box, ignition key, camshaft sensor but no luck. Do anybody know if this jet boat has a slant sensor as like the jet ski they have this on the side of the fuse box. Also so i try swaping crankshaft sensor? Any help will be appreciated.

Have you checked the clean out port hatch switches or the kill switch lanyard? Both could prevent spark.
 
Moved this to its own thread so it has better visibility.

I would try either shimming the lanyard switch up higher or jumping the switch out. Other possibility is your 12 volt primary to the coil is not getting from your ignition switch to your coils through the ECU. That could indicate a broken or wet connector.
