No start, stuck in gear??

[Mburt92 0]

2014 centurion enzo 233 with a 5.7 pcm.  Ran great all day on the lake, shut it off to get tube ready to pull and then boat wouldn't start. Had some issues last summer where it wouldn't start but if I wiggled throttle a bit it would fire up. Only way I could get it to go this time was by jumping starter solenoid. Boom fired up go to put it in gear and it would rev up but wouldn't move. Since then I've had it in my shop testing switches, throttle, tether  and all seem to be good. Is there a neutral safety switch on this thing anywhere? Is the transmission piled up? Or does anyone have an idea of what to check next? I've got it narrowed down to the relay not getting a ground because as soon as I put a ground to the starter relay it will fire up. But same thing as out on the water it won't spin the prop..
