We have had our 1989 17ft Skeeter boat for two seasons now, and we have had it on the water over 50 times. I have no idea how large the gas tank is on the boat, I fill up the boat every time I we come off the lake because I do not ever want to run out of gas on the lake. Does anyone know what the standard size gas tank is for this boat? I do not want to have to drain the gas tank to find out. Thank you in advance for your time.
