Pro XS Vs. SHO

["W"]

Ok......I have been doing some work on the Sho....because I'm thinking about getting one on my next Haynie..
He is what I have found
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...

According to both manufacturers the weight on both engines is 505 lbs.

Yamaha does not "demo" loose engines...guide or not. Yamaha only demos packaged rigs like skeeter. (yamaha owns skeeter) My dad has worked with yamaha for over 20 years along with being on skeeter's factory team. Not trying to prove anything,but that is the cold hard FACTS.

I agree on the weight but were are you facts on fuel burn? I do not have a Mercmointor but when I'm doing 45mph at 3500rpm that has to be pretty good.

All I can tell you is yamaha tested alot comparing the sho to a opti before they released it. I have no literature on a EXACT same boat setup comparing a opti to a sho. To each his own,yamaha stands behind there product 100%.
I much rather have a jap made engine than a mexico and china made engine. For example,Mercury has been having ignition coil and lower unit problems for years on the opti. They have too many of the older non updated product and are getting dealers to install them instead of fixing the problem with a updated product.

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. http://www.yamaha-motor.com/outboard...ctus/home.aspx

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.
