Hey guys... as those of you who know me knows I just bought a new (used) boat. Its a Rinker Fiesta Vee 300 with Twin Mercruiser small blocks carborated. I will pause for you to regain composure as I know 520 HP is a joke to you all. Those of you who know me well knows Im the furthest thing from a gear head, however my friend Tom noticed that the Carbs were double barreled as opposed to 4 barrel. His assumption was that Mercruiser must have come out with this for Fuel efficiency, however, but will also limit my speed and RPM's. Now I know that we are not talking major speed, but would it be worth it for me to consider changing the carbs out to four barrel to increase my RPM's and speed some or should I just stick to 35 MPH and enjoy the fact that I will be choaking down far less fuel at $6 a gallon? Tom had never seen this before and wondered if you all were familiar with this approach by mercruiser. thanks
