Just wantting to know more about a hydraulic jack plate 10" I have a 99 triton 180 with a johnson 150hp with a 23 pitch prop. two men, tackle and gear runs about 58mph. If i was to get a 10" hydraulic jack plate how much more top speed would i gain, would i be able to go to a bigger pitch prop and still have the hole shot that i have with the 23 pitch prop. Don't know much about the jack plates, please help!
