Juicing up a 7.4 mercruiser

[nuboater]

Is there a blower available for this motor? If so what kind of improvements can I expect? I have a 99 laveycraft nuera. I want to run mid-high 70's (but would like 80) any suggestions?
thanks

I put a B&M 174 on my 7.4 carb motor with Nickerson carb and blower cam.I saw about a 10 mph and alot better acceleration. Whipple makes a lot more power than the small blower I was running and you most likley have fuel injection. Still have the blower and carb its on the work bench.Removed it to sell the boat... Bob

BobHey 737, so does that mean its for sale? If so how mucho. I wonder if they make a manifold for the 4.3 V6! I'd like a setup like that for my truck.
