Wide mounted twin outboards on monohull

Again no, not on a monohull but there is no reason you couldn't do it, especially on a long skinny hull.
You can manually trim most o/b's from the trim tab on the bottom of the cav plate (which is actually an anti-ventilation plate but nobody calls it that).
However, be warned, this is likely to reduce your resale value because, as your about to see by all the negative responses, this is an unconventional design characteristic.

EDIT: I've driven lots of twin engine boats on one engine. The asymmetrical thrust is a minor issue. Some catamaran sailboats use only one 9.9 mounted on one pontoon and require very, very little rudder correction.

I've seen an off center OB. On a semi catamaran hull. It worked ok. Slight steering adjustment, but workable.

Semi catamaran? Something like that Aspen catamaran?

Agreed
 
If you're clever in the design of your transom, you may be able to make it easier to convert to a traditional centre mount down the road.
 
Wait, why not a side door?
 
Most search and rescue boats use side doors.

Commercial fishing? I thought this door was for freediving.

Regardless, one consideration is a transom door would be subject to lower pitch angles
versus a side door which would experience higher roll angles, especially in a skinny boat, potentially.
 
Pitch vs roll. Excellent point.

Just thought of this... Side doors are likely more expensive as far as I can tell. The transom door in the picture above is a piece of acrylic with hinges and a latch. Maybe $50. Making an operating, safe, and decent looking side door might cost more.

It may be more work too but what's the objective, to cost the least or best suit your needs?
 
I found the boat I was thinking of. Solace 345. I couldn't remember who made it. A coworker reminded me. I think it is a little too out of the box. It might be discontinued judging from their website.
