I do agree, that you probably wouldn't ahve that much ore to gain, but
I suppose it depends on what you want. For pulling a ski , i would
think you could get a better hole shot, and plane out quicker. But I do
agree,t hat you probably wouldn't notice that much difference on top
end.



But even so, arn't the fron two bbls. usually smaller on a 4, and the
bigger back two usually kick in at 3/4 to WOT?

I recently purchased a 1988 Sea Ray with a Mercruiser V-6 4.3 with a 2
barrel carb (175 hp)
Is it possible to convert this to a 4.3 with 4 barrel carb (205hp)
Is it just a matter of changing the carb and intake or are the
ingnitions different?

Any input would be greatly appreciated.
