Okay folks I just bought my first Bass boat it is a 1992 Ranger 372V with a 1991 Evinrude 150 horseIntruder. My question is can I use Stabil and Seafoam. Both?(In the same tank of gas) and how often should I use them? One more question that popped into mind this boat has a Evinrude foot controlled trolling motor probably, came with the boat does anyone have any idea what pound of thrust it might be? I can get model #' s if I need to.
