Hey guys, I'm new to the forum, I have a 1990 Conbrio. I bought it about 8 months ago and I love the boat, it runs great. My only issue is that the carbureted 351 really likes to drink the gas. I went out just to chill last Saturday and I had 1/4 tank in it, I drove out about 5 miles and barely had enough fuel to make it back to the ramp. Do any of you know of a prop size, pitch, and number of blades would help out on gas a little but still be good to wakeboard with?
