Ok airboaters. I recently purchased a 17ft Panther with a 383 stroker and 78" 2 blade whisper tip prop. We took it out the other night and fished for 4 hrs and never got above 2000 rpms we put in close to where we fish so didnt need to go fast. In four hrs of easy use we burned 20+ gal of premium fuel. Is this normal? Seems excessive to me but I'm new to this. I didn't expect airboating to be cheap but i was kind of hoping a 40gal tank would last long enough to shoot a tournament.
