A question regarding the Mercruiser 260. Does it come in both a 2 barrel and four barrel configuration? And if so, is there a note worthy mpg disparity between those two variations?

easy way to check, with the engine off, pop the flame arrester off and push on the throttle and see for yourself.. do you see 2 or 4 barrels? pretty sure most mercruisers v-8's are 4 barrel

Actually I don't own the boat yet. Just considering it.

Ayuh,... 260 is the Horsepower rating,... That's with a 4bbl. carb...
If a 2bbl. carb is installed,.. It'll be Less than 260hp...

So to answer your question,.... No...

roughly 30-40% difference in mpg between v6 and v8, I own both (different size boats)
