Is there any truth to the rumor that Yam is working on making a 300sho?

Id be suprised to see the 225 sho faster than the 225 Pro XS, Maybe even The regular Obama Max. Not by much, but possibly.
Reason being I Know of three of the exact same hulls 1 running a VMAX HPDI 225 Running 60mph, another running a 225 Obama Max running 62mph, and another running a VMAX SHO 225 running 60-61mph. And the 225 pro XS has more HP. Now this is one paticular brand of boat some motors act diffrient on diffrient hulls. JMO

The compressors are probably the most problematic item on the Optimax. They can fail with no warning. But, when they do, you have to change out all 6 plugs, and sometimes, an injector. If you want to keep your compressor from qitting on you, there is way. It requires the lower cowling to be removed. On the port side of the motor, there is a plastic filter that screws into the lower part of the head. This filter, if clogged, will shorten your compressor life span. If you stay out of the shallows, you shouldn't have a problem. Like Montauk stated, shells and grasses can cause the compressor to overheat and fail. It's our biggest problem at the lodge, along with lower units.

Sorry I was talking about the 250sho being faster than a 225 merc. 225 v/s 225 or 250 v/s 250, the Merc still wins.
