    Any red flags with my YDS ?

    21 hours ago
    * 2002 F115 220 hours

    Hey all, I have been trouble shooting an intermittent power loss up top and an intermittent stumbling at ideal issue for a few months now. I will link to my original post where I go into great detail about the issue and outline all of the steps I took to remedy the issue. Unfortunately , I spent much of the the season trouble shooting with no luck. Now, spring is approaching and I really want to have a reliable boat before summer. I am suspicious that my intake pressures are too high. I have done a compression test and everything comes back great. I am waiting on a leak down tester in the mail. The motor only has 220 hours so I would be surprised if a valve is leaking... but I figured a leak down test would be a good place to start.

    Question: Dose anyone have numbers that I can compare my YDS too? Or can anyone look over my read out and ID red flags/areas of interests.

    Thank you in advance! Love this community !

    Hi,this is just my humble diagnosis.....your diagnosis record indicated error recently at 208.2 hrs.Your TPS voltage/throttle valve opening is out of specs...u may need to link & sync to specs.
