Have any other 2001 SangAir owners had problems with the internal ballast system not priming? Have you had any problems with the tanks draining when under way? <BR> <BR>I've had nothing but problems with the dual tanks beneath the back seat, and I was hoping someone might have some insight to any similar problems they've been having. <BR> <BR>While on the topic of internal ballast, has anyone ever attempted to put additional internal ballast in one of these boats versus having 1500 lbs of fat sacs laying all over the floor of the boat. <BR> <BR>I'd prefer not to use lead and have to trailer it with me where ever I go. <BR> <BR>Thanks for any input. <BR>
