I have a 18 footer with a legend jet drive and a 4.3 V6 mercruiser (chevy) motor. This motor has the stock 2BBL Rochester carburetor with a rather tiny flame arrestor. I have the following questions:
1) Would spending 120 bucks on a bigger K&N flame arrestor really make a difference in this carb?
2) In order to get more power, which way would I be better off going:
a) change the carb to another 2BBL (I am looking at the Holley 300 CFM Two Barrel part# 0-80320-1) and keeping my existing intake manifold, or
b) go with a 4BBL holley 600 CFM part#0-80492 and incure the cost of replacing my existing intake with a 4BBL intake.
Please keep in mind that this is just a family boat and all I am trying to do is to get the kids up on skis and have no intention of racing or anything like that.
Thanx in advance for all recommendations...
