    Very nice! Er, when are you getting the P60?

    Cheers

    hmm, I fear you may be right, i'll have to get it checked.

    But do you have any flashing LEDs? You would if it was a limp-home mode activated by the EVC. Also it's a bit unlikely that both engines would have an EVC-detected limp-mode fault

    I don't know D12's, sorry, but if they were both in gear, throttle positions broadly the same and one was in reduced-power, wouldn't the other one just sync down to the reduced-power rpm?

    No flashing lights, and no excess smoke. Maybe fuel shortage - ugh, maybe fuel bug :-(

    I haven't completely discounted fouling though, so i'll lift and clean first

    That second vid is mighty impressive. I'm going to show my SWMBO and see if she'll let me buy a boat big enough to accomodate Seekeepers. She hates the boat rolling around at anchor....

    As to 1000rpm max, sounds like you're dragging a trawler net to me.... I assume you didn't forget to antifoul last year

    Ok, here's another thought.
    Since jfm mentioned EVC controls, I suppose you also have the digital display which can show all the engines parameters.
    If so, you maybe noticed in the past what sort of load there is normally on the engines at 1000 rpm.
    And even if you didn't, it should be pretty low - somewhere between 20 and 30%, as a guesstimate.
    Now, if it takes more power to keep the boat moving at 1000 rpm (as it should be the case if the fouling would be as bad as you suspect), the load has to be MUCH higher.
    Actually, if the engines can't accelerate further, in theory they should be running at close to 100% load, even at at such low RPM.
    In turn, that would explain why the boat can't go on the plane, because it would take more power than the engines are capable to produce.
    All rather unlikely in my opinion - I tend to think that there must be some other reason - but easy to check without lifting the boat, anyway.

    don't think I can contribute to this 1000rpm issue, but if it was the first outing of the craft after the stab fitting, maybe something silly happened on installation? dunno bent fuel line, blocked air path.

    simply, when something happens/fails I tend to go back to what was altered recently and I've saved a lot of time (ok, due to my stupidity in the first place, but that's another story )

    V.

    PS. and to be on topic, second video 26+sec is really impressive, well done!
    PPS. I can see Bart starting saving money NOW for next year's BA project work

    I don't have the digital display, just the EDC controller with 5 buttons/6 LED's. I need to lift and anti-foul the boat before Easter anyway (and i'm not visiting again before it is lifted), so I may as well see how much fouling there is, or if there is something else obvious causing the problem when I look underneath, before investigating other possibilities.

    That's a good line of thought Virtuvas, although the gyro system is independent so its hard to see what could have been disturbed
