1981 Motor Boating Magazine v20 with Merc 200hp

I often notice on "Performance Bulletins" that if the same boat is tested with a 225 and a 250, the 250 almost always gets better mpg and top speed...but it seems that if the boat can be pushed above 40 mph with one of the I-4 motors (150-200), they get better mpg than a V-6 (200). If the I-4 won't do 40, they suck more gas than a 300.

real world, bgreene, your looking at 4-4.25 mpg. giving you a range of 200-240. still double that of a 2S.

at 32mph i'm burning 7.5-8.5 gph. depending on load & conditions. with the curtains up on;y 28 mph.

good info, maybe I will keep the 2.4 200 on my V, still got the 250 EFI sitting on the stand

That's at 4200-4400rpm.

That's good for 60 miles out......far enough to get on tuna, 60 back, 60 reserve.
