I own a '79 Sterling bubbledeck jet boat. Has a 16" wide flat spot 2/3 of the way down the hull. Looks like the Sanger. Anyone heard of these boats. I know the company was in Florida and is out of business. I've beed working on it a little at a time. It now goes 65 mph on gps but I think more is there if I work on the pump. BB 454 -400hp, A impeller-jg berk pump. I have a big motor I can put in it but want to get the most out of what I have first.
