Looking at a 2006 Crownline 250CR with a carb'd 5.7 Merc with a Bravo III. I know it isn't a SR but would think the max RPM would be the same?

Survey and sea trial are penciled in for next Sunday the 29th.
 
If it is a Merc then should say on it's cover assuming the number match. In my experience, the lower end of that range (44-4500) give the best performance/economy for boat that size. Your intended use may differ from mine though.
 
Thanks. Been a hectic week but survey and sea trial are tentatively scheduled for either Sunday or Monday. Have to call him tomorrow to get it scheduled. The shop where the boat is at is supposed to get it ready and running on the muffs to make sure everything is good there. It has been sitting for almost 3 years.
