    Here is a video from YDS where I was attempting to catch the cutout and pressure drop in both LP and HP. But the motor just needed to be shut off before it died.

    This is what the plugs looked like this morning after running for 2 min. Was clean right before. I also took some video of YDS I will be uploading momentarily, but I couldn't rev it high enough to see the pressures drop because the motor was running so poorly (popping and sputtering, of course...

    Hi Everyone. I am in desperate need for ideas on why my 2002 HDPI 200 z motor is sick. I think it is important to give a quick backstory on what I have done so far. When I got the boat it was a year before I could actually put it in the water. I started preempted maintenance last year. I found...
