So Imagine 2 scenarios:
1) The boat is cruising with no ballast, the wakeplate is down and the engine is at 3,000 RPM's and the boat in turn is doing a speed around 25mph.
2) The boat is loaded with 3,000 pounds of ballast and is likewise turning 3,000 RPM's at 10mph.
So, with the two scenarios, once the boat is up on plane and cruising; is it using the same amount of fuel for both scenarios because the transmission is a 1:1 and the RPM's are the same despite the different respective speeds?
It seems to me that because our boats have a 1:1 transmission, that if you hold the RPM's constant at 3000 RPM's, that the fuel consumption would likewise be constant and the variable would be the speed that you'd then go as you added weight to the boat.
