Best Cruising RPM for SD2400 with Merc.350mag with Bravo3

Hi All!
I know this subject has been written about but I can't find the post I'm looking for.
I have a 2014 SD2400 I/O Mercruiser 350 Mag with a Bravo 3 drive.
I'm looking the best cruising speed RPM for fuel burn in GPH (fuel flow)….speed vs burn…all else being equal, properly trimmed…etc. I have the numbers for the engine itself…but that doesn't take into consideration the size of the boat…just engine. Same engine on a different boat might go faster on a smaller boat, slower on a larger boat.
Has anyone installed a fuel flow meter on this boat and done the analysis best rpm for best speed vs fuel burn?
One of our favorite restaurants is about 1+45 away and if the fuel burn/mph is more efficient at a slightly different rpm then its a no brainer. I've been running between 3000-3300-3500 rpm but just can't tell the difference without a fuel flow gage. Any SD2400 owners played with the numbers and settled in on a good cruise rpm?? THANKS!!!
