I'm new to the site and bought my first Aquasport last year, so I'm still learning this boat. It's a 1986 20ft. Walk around with a Cuddy Cabin and I've repowered it with a 200 eTech. I ran out of gas this weekend, fuel gauge showed 1/2 full, and Sea Tow sold me 5 gallons to get back in. When I topped off, I could only put in 30 gallons, so I'm guessing that my boat has a 36 gallon tank. I was hoping it was larger, but will just have to accept my limitations. I live on the Gulf Coast in the Big Bend area and the better fishing is out there.
