1981 Motor Boating Magazine v20 with Merc 200hp

[randlemanboater]

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.
