Hey guys, new to the forums. Recently squired a new to me 97 Ranger 518 with a 97 Venom 200 on it. Boat itself is in really good shape for 20 years old aside from some cosmetic and minor mechanical issues. Motor seems to be in really good shape and I've put a little work into it getting it running well. I've cleaned out the carbs, redone some fuel lines, new plugs, minor stuff like that. It idles good and revs up good, starts with little effort, goes into gear fine, and will even get up on plane pretty quick. Issue I'm having now is that as it approaches plane and once it's on plane, it begins to miss. This happenes as it tops 30-35 mph according to the speedo on the dash, and I'd say 3000-4000 rpm. This happened the first time I took it on the water and every time since. As long as I keep it around 30 mph it runs fine. Now I'm no speed freak but I know a 200 hp motor should be pushing this boat way faster. I've run about 15 gallons of premixed 50:1 gas mixed with some sea foam and no change. Have double checked everything I can think of and still doing it. Any suggestions or things that I might not have thought of?? Any help is appreciated.
