Please do not multiple and divide my rough scale to get all kinds of intruputations (sp) of what my boat does or does not do; its what scale or chart that I keep in my mind to use, roughly, and not intended to be perfect. Example, I do not WOT much and doubt if the fuel burn is very correct. Same way with the 4 and 7 mph numbers, again, for example.

I am still trying to find the "sweet spot" for my boat.
Its not so much that I don't want to spend the money, as much as it is that I'd like to run the boat the most efficiently.
I would like to put in a fuel monitor, but my engines have a funky fuel delivery system that most of the fuel flow metering systems won't work properly.
So until then, I guess I just need to make some long distance runs at a given speed and RPM and see what looks the best.

I would think 3000 RPM's with your props and weight of the boat, will yield the best compromise of cruising speed and fuel burn efficiency. But, I'm just guessing.
There might not be that much difference between 3,000 rpm, 3,500 rpms, and 4,000 rpms as far as fuel burn is concerned. But usually by 4,000 rpms the burn is going up quite a bit compared to 3,000 - 3,500 rpms.

Thanks for the post seabuddy. Your numbers, along with Al’s recent post mentioning 70 gals in four hours... it puts perspective on the fuel cost associated with a 30+ft boat. (never mind other associated costs)

If there is one person that can figure it out - it is you Al
