"I have a big block chevy with a Holley 4011 carb. I run this motor in a 28 ft. Tollycraft. I generally cruise it at 2800-3000 rpms at roughly 12 knots burning 10 gal/hr hour measured with a fuel flowmeter. I run it usually just before the secondaries kick in. Frankly much faster and it gets too noisy. I also fish with it, trolling just at idle.
Since higher performance is not my goal any tips on carb tuning for better milage and if possible slower trolling speeds?"
