Sea Ray 340. On topic, but be warned.......

Most people won't run a gasoline engine wide open for extended periods of
time, but backed down to 4000 rpm we observed very respectable cruise speed
readings averaging about 25 mph.
=========================================
4,000 RPM is way too fast for reliable operation and decent longevity
on those motors. 3.200 to 3,400 RPM is generally regarded as maximum
cruising speed for gas engines of that type. At 3,400 the boat would
be cruising at 17 to 18 kts which is slow for an express.
It sounds under powered the way it was tested, and it's usually a
mistake to buy an under powered boat. I'd personally order the boat
with bigger gas engines if available, at about 350 hp each for decent
cruising performance in the low to mid 20kt range. For frequent usage
diesels would be an even better choice, and they will return 40 to 50%
of their cost in resale value.
