306 canyon - do engines touch water when raised?

I never understood why the engines need to have the bottom a couple or inches in the water. When I see my same model with twin Suzukis that stay dry when raised. So is it an engine issue or a boat issue.

It's a bit of both. It's whether the engine/engine hood size/design is such to allow more clearance when tilted up AND whether the boat manufacturer designs enough clearance at the stern.

That GW did not (or only in the last years) solved the wet transom problem in more than 30 years is very disappointing for such a top tier brand. I consider GW far superior in build and ride quality than BW, but the rather simple solvable transom problem is just frustrating and expensive to fix.
My 2011 306 Canyon is in the shipyard and fibreglass specialist should repair the swollen transom, but still waiting for a quote.

The problem with submerged lower units is rather common, particularly on pre 2005 hulls being designed for lighter two strokes but i see that even on newer and new boats. It is either a design flaw regarding center of gravity or the choice of a low transom with short splashwell as both limit how much the engine can be tilted up. On most dual outboards hulls a higher transom is not really a issue while on single or triple outboards it can be a issue as center engine length may be too short even on a 30" outboard.

In case of my 306 Canyon, i can't tilt my BF350 more up, tried to set the digital tilt limiter to zero but from what i understood there is no limit set. That steers me to believe that GW just miscalculated the COG and never fixed that, maybe the new design Canyon with the different console style does better.

Didn't solve yet to my knowledge. Going to the boat show this weekend and will check.. Just a bigger stainless bang plate to sell it. As we used to say in the electronics biz, sell your issues as a feature.....
If I ever buy a new one, I will require the factory to do it correctly before the engines are mounted or no deal.

Shipyard offered me the same, but i wan't to have it repaired correctly.
I don't think that the bang plate is the only problem, i expect that the transom design is just a bit too weak and flexes.
Either because transom is too thin or not correctly bonded to the stringers.

The do that because
a) the engine wight is less
b) the engine can tilt a bit more
c) a combination of both

All GW's i saw had OEM Yamahas and the lower unit is a few inches submerged, including the 330 Express.
I also saw a 2001 Bimini with Suzuki DF250's and lower units were partially submerged.
