I've got the same boat, same year, same engines. I just got it late last summer. I only had it in the water for a month to see what needed to be done over the winter. I haven't figured out the fuel usage yet. I have gone through it from one end to the other and I'm always finding something new (or something that needs renewing). You've come to a good spot

thanks Tig....

of course the harder you push on the loud handle...the more gas is sucked into the burn centers.....needless to say that chart clearly shows how much gas is gonna get used at what rpm...
