I just sold my 1987 Supra Sunsport and loved it, now i'm needing some info before i buy my next supra.

i'm looking to buy a 2006 24ssv, my last Supra was direct drive and now i want more room for people and storage.

what i would like to know is what is the fuel consumption on the 5.7L and the 8.1L in that boat, and secondly would the 8.1 with a prop upgrade be pretty much the same consumption.

I mostly wakeboard and wakesurf and when i cruise around it's mostly 30-35mph, not a very big lake. we're usually 6-7 in the boat and when we wakesurf i usually put an 1100lb in the rear with front bags 100% full

it's not a question of not being able to afford the gas..... i'm just wondering if the 8.1 is overkill, or if i can tune it a bit to be a little less of a gas guzzler. i'm not familiar with the transmission gear ratios, but i'm guessing the 5.7 would run at higher RPM than the 8.1 at the same speed.

any help anyone can provide would be much appreciated,
thx
