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 yearAdrian

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 )
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
