Fuel mileage is better on Opi max vs Sho on same boat...
Sho is heavier vs Opti Max
A guy ran a Sho 250 on a Trition for one month and ran the Opi 250 on same boat
He burned almost double the fuel with the sho...said fuel mileage is horrible
This is a guide who had the Sho to demo...

The SHO and the Merc ProXS motors (3.0L) show their weights as 505 lbs.

I agree that IF the SHO was more fuel efficient, then rest assured Yamaha would have that posted on their website. From my experience it is very close.
That said, I have owned the Merc 225 and 250 ProXS motors and now have my 2nd SHO on my 2nd new boat. The SHO is very impressive - quiet, efficient, big time torque & excellent top end - despite being a 'Year' 1 product. There have been a few TSBs on the SHO to modify the thermostats and water pickups, as the early models would not get to desired operating temps in ultra cold water situations. My 2nd SHO had them done at the factory, so all new SHOs should be good to go.
With a motor serial number, the Atlanta Yamaha Outboard folks can tell you if the SHO you have in mind is up to spec. As you try to make your decision call the Yamaha Outboard guys in Atlanta and ask them about the SHO, saltwater use, etc.

Also a number of boat companies have performance data on bay boats with the SHO from Scout, Maverick, Pathfinder, Skeeter, etc.
The LMC guys sell Mercs and Yams, so maybe go talk to them too before you decide. They do my SHO service work and I have been impressed LMC.
Good luck.
