Just trying to find out best plan before spending more money. i did just talk to GT marine out here who worked on a 37' Stilletto which did race in the Catalina Ski race once with 1050 Quad Whipples with # 6 drives and they used 3' spacers and turned the drives around to spin out (which lays a wider wake for the skier). Will try this first. need to get ahold of 2 - 3" spacers to buy if anybody know of any used.
