  • F115 flooding problem

    I have a 2005 F115 that has no more than 100 hours on it. I have recently experienced a clogged VST filter.

    My brother and I changed the VST filter recently. We put the boat in the water and it seemed to be exactly the same as it was before we replaced the filters. We changed the spark plugs and tried it again and it seemed to be worse and started skipping on the #2 cylinder. Pulled the plugs and found the #2 cylinder to be getting WAY TOO much gas. Checked the fire and found the plug to be firing just fine. The cylinders all had great compression. I thought it may be a bad injector so I bought a new set of injectors and put in it. The problem is the same, #2 cylinder flooding with fuel. We swapped two injectors around and it is still the same.

    Any suggestions on what I can check now?

    I have not had a tech download the computer yet. Just curious if there is anything I can check first.

    Thanks for any help anyone can provide.

    does that motor have a lift pump run off of the #2 crankcase?
    Just a thought, 2stks had problems with leaking diaphragms some times
