1993 Eliminator 21’ 350 Chevy magnum, Alpha 1 w / new edelbrock 4 barrel carb. Boat was completely stripped down and refurbished last year; so yes, restorer has it stripped to the gills; whole new interior installed. I’m losing gas somewhere as well ... overwhelming so! Could they have plugged the vents when they were color sanding? Makes sense they might have! I’ll check that next. TY GUYS!
