would it lean to the right or to the left ?
And which lean does motormount to the right correct ?
I would suggest that much easier for you than moving the console will be to fit trim tabs. "Chris" on here has fitted two sets but I can't seem to find his threads. "Erin" detailed his in the link below. It would allow you to lower the tab on the left hand side which raises up that side by creating more lift at the stern. On the canals it will also enable you to plane at lower speeds which I imagine will sometimes be useful! Loading evenly matters much less because the tabs can be used to counteract any imbalance.

Interestingly, my boat leans to port when underway even though the engine is mounted about 30mm to starboard. It also always dries out port to I suspect the layup is not perfectly balanced. Having the battery to port may not help. It has never been a problem running with a slight lean to port, but I can now correct that with tabs. I also raised my engine but didn't notice any appreciable difference.

Prop type can have a big and surprising impact on boat trim. When we first bought pigs ear it had a laser 2 prop on the Honda. When we switched to a large diameter Mirage prop the difference was huge. The boat ran flat and even when coming out of the water it has no tendency to twist to port.

Balance will help when stationery or at low speeds and moving the battery to starboard would help Erin but once you are are planing the torque affect of the prop is what affects the trim.

I would try some different props before changing anything.

Port lean can also having to do with current and or wind direction

I also have it 'sometimes' on the scorp - deep v ribs are sensitive to that

Our 6.3 op leans to port when trimmed in, as we trim out it balances up to neutral. Ours too sits v low at the rear, it's just the design. Freeboard on transom is excellent though. Tubes drag slightly in water but gives great stability.

Where are your tanks? We have 140L in console. That should stop chine walking. Ours only just chine walked at 52mph... It's v rare though, we need to be v lightly loaded with no kit on.

The 200 must fly.

Yes, boats with a lot of "windage" (e.g. a Cabin RIB) will often heel INTO a cross wind, which isn't what you might expect...

Yes that is odd. How come?

Damned if I know why, but it does. I've noticed it while helming a twin rig running counter-rotating props. I'm sure Phyzzix has the answer...

'we need to be very lightly loaded WITH NO KIT ON'
not a problem in present weather conditions then
