I've been running the Stargazer in rpm mode for quite some time due to recommendations from Perfect Pass. We don't drop at each end and the PP doesn't recover well out of turns hence the rpm mode. I run it at 3600 rpm and that starts me into the course around 35 and keeps my minimum around 34. I'm 45 and am happy to ski 34.2 mph. The boat is a 1999 Ski Nautique with a GT40. Prop is an Acme 422. We have been toying with the Slalom mode. After the turns the boat is just not there. The line is taught but I am not getting any acceleration until I hit about mid wake and the the boat pulls on me. It's way to late for the pull and I really dislike the speed mode. The course times in speed mode or rpm mode are good but the boat feels like a darn yoyo at 34.2 in slalom mode. I'll put it back into rpm mode and the boat is there and fells more even. I can come out of my turn and lay into the rope and get the proper acceleration. How can I fix this lack of boat response and delay in the acceleration? It almost feels like the boat is slowing when I want it to speed up. The course was gps set. The PP does beep a bit early but we set it exactly as in the manual with the buttons pressed as the pylon was entering the gates. In speed mode the rpm's are typically lower than 3600 but they spike up and down 100 - 150 rpms. The mph on the gauge is more consistent in rpm mode than mph mode as well.
Does z box fix this?
Do I need to get a 343 with ZO? (or a new boat) the motor and ZO are still way cheaper.
