What would be the fuel burn for each. To damn much?? LOL
I am thinking 5-6 cruise and TDM for WOT
And could you run slower than 18-20 without issues to nav or engines
Have a great day
Thanks in advance
I run 210 Cummins on my Symbol 41. I cruise at hull speed most of the time and burn about 4GPH total between the two engines. This is running them at about 1400 RPM.
No idea of burn at 80% throttle. I have no reason to run the boat 5 knots faster for a lot more fuel usage. You can run your engines all day long at a lower RPM without any issue on these engines. As long as you are up to temp on the engines there are no worries.
