approximate fuel consumption for ScarabIII and Mercruiser MCM370hp
I am looking for rough numbers for fuel consumtion for a pair of Mercruiser MCMs rated at 370hp.
Ideally a rough indication for various speeds / RPM would be good...!!!
I have a number at the moment of 35 GPH (for BOTH engines) that gives about 45-55mph....
Any other numbers from you guys?? Especially lower speed numbers.
Cheers
Stef

...and that would give about 35GPH for the pair?

Zackly why i was after GPH / speed for maybe 1-2-3000 revs...

THIS IS FOR 2 ENGINES!!!!
Got some interesting numbers for you… RPM v US Gal per Hour Consumption for 7.4L Mercruisers:
1000
3.5
2000
6.8
2500
18
3000
23.3
3500
30.8
4000
43
4400
50
Thought you might find these useful – you can add your third column of speed to get an interesting idea of range etc
