the boat I just bought has a steel gas tank that says 'Johnson' on it, which leads me to believe that it was purchased with the engine (1972). <br /><br />From using it Over the years, I am sure that there is a ton of buildup in the tank...would it be a good idea to go ahead and get a new tank, maybe a plastic one for weight?<br /><br />Just curious. Planning my first trip ever tomorrow, wish me luck!<br />Thanks!<br />Shawn
