Looks like a niche product to me. They are big heavy honkers.

True, but 300 hp gas outboards are not exactly feather weight either.
I think the biggest issues right now are parts and dealer support.

The Yamaha 300 is about 550 lbs, and the Cox diesel is about 825 lbs. A bit heavier for sure.

Yes, but not really a deal breaker in my opinion. Consider that each
of my 300hp DD 6-71's weighs over 3,000 pounds, and a more modern
Cummins or Cat weighs well over 1,100 pounds plus transmission and
drive train.


Absolutely. Given the other specs that extra weight wouldn't be a deal breaker, if one had the bucks
at about twice the cost of the Yamaha 300.

As I said it is a niche product, probably for barge pushers and that
rare "tender" for a diesel yacht that has a 300 HP motor or two and
they don't want a separate fuel supply.
I am not sure it will be that attractive for "go fast" center
consoles.
I do notice that they are hanging outboards on bigger cruising boats
like the 42' Freeman Jimmy Buffett just bought. That might be a good
fit.


Four 350 hp four cycle gas engines will weigh what, 2000 pounds for 1400
hp? And four of those 800+ pound diesels for 1200 hp will weigh 3200
pounds? That Margaritavilla boat would have to be redesigned, I would
think, to sling that much weight on its butt, and it wouldn't be as
fast. Plus, the guys running four huge outboards on a go-fast fishing
boat probably don't give a damn about fuel burn.

A Yamaha 350 outboard weighs 763 lbs dry. You may want to break your calculator back out.
