    Launch day. A bit late in the season with all the craziness of spring but fired right up. Still need a good topside wash and wax (hopefully get crew there in next few days) but at least floating. Still have one waverunner to get in, but everything else is wet

    Been chasing a rich condition since last summer. Boat was slow to get on plane, had some black smoke in exhaust, burning fuel more quickly, and hard to start when hot. Removed and tested the engine coolant temp sensor, hoping that would be it. Test showed it was operating within limits, but I replaced anyway (not expensive), and kept it for a spare. Removed all 8 spark plugs and each one was pretty heavily sooted up. I was quite happy with that result as it should mean a global fueling issue rather than say a dead cylinder, or bad fuel injector, etc. 

    I initially proceeded to soak and clean the old plugs and reuse, but then decided to buy some new ones and start fresh. Old ones cleaned up pretty well, so will keep them for spares. 
    Next stop was to pull the fuel pressure regulator to check for debris clogging the screens. Apparently there was a service bulletin from Volvo Penta (P-23-7-3) sometime around 2012 addressing issues with paint inside the fuel pumps being "released" into the fuel system and clogging the fuel pressure regulator screens. The service bulletin recommends removing the screen filter and replace it with an E-clip.
    This sounds promising as it could account for the issues I've been having with the boat, unless, of course, the service bulletin fix had already be completed. So, with great anticipation, I removed the fuel pressure regulator and found this:

    For comparison, below is the filter screen after I cleaned it:

    Looks about 80% blocked. I think this may be the root of my problem. Hoping to splash the boat in the next week, so will report back then. I ordered the E clip to complete the fix as per the bulletin, but it is not arriving till late July, so I'm running the cleaned existing filter screen until then. Kinda sucks being so late to launch, but at least we have a long boating season where I live (I wish! I live on the east coast of Canada. Our boating season is about 2-3 months long). 

        
    Just a note that I have owned the boat for 2 years. No issues with fueling till last summer. Still working my way thru the boat maintenance.

    Wow, looks like that needed to be done regardless. Good find.
