I think the problem that Yamaha has to overcome is that they brought out the F350 first and then announced the F300 later. Just how many F225's do you think they would have sold had the F250 been out first. In the past for the most part it has gone up in HP not down.

Actually this is not true at all. In the history of outboards it is far more common that when a radically new platform is introduced, a relatively high horsepower model is brought to market first and then smaller horsepower derivatives are brought in to fill the gap even as more and more refined versions of the original are developed which often lead to more powerful models.
I am old enough to remember the introduction of the V-6 outboard, OMC's Johnson and Evinrude 200. This was the summer of 1975 and at that time the most powerful outboards were OMC's 140 V-4 and Mercury's inline six 150. A 200 HP outboard was almost incomprehensible back then as that was the realm of V-8 sterndrives.
This 1976 Johnson/Evinrude 200 was then followed up with the 175 and 150 HP versions in 1977 and 1978. Likewise Mercury quickly followed suit to introducing their first V-6 outboard, the BlackMax 175 which was subsequently followed by the 150.
OMC then tweaked the V-6 to make their 235 HP model and Mercury upped theirs to 200 and then 225 HP.
When the first four-stroke V-6 was introduced, what HP was it? That's right, it was Yamaha's F225 which was then followed by the F200 and only later the F250.
It is pretty obvious what Yamaha is doing. They introduce a very big and robust new outboard, the V-8 four-stoke at 350 HP. They follow that up with a 300 HP to fill the gap between 250 and 350. Duh. It is quite obvious that 5.3 liters of displacement is ultimately going to yield far more than 350 HP. I guarantee you Yamaha will introduce a four-stroke 400 HP outboard based on this motor.
