Hey all, this is my first forum post so bear with me. Also, I know this topic has been discussed in other threads, but I wanted to discuss the exact details of my situation. I have a late 90's 200 Johnson Venom behind a Sprint 297 Pro. The boat is 19' long. The engine starts and idles fine, but throttle response seems sluggish. It takes too long to plane off with just myself in the boat, but will not plane off with two people. When taking off, the engine will rev between 2600 and 2900 rpm and the boat will not get up. I don't expect the boat to be a hot rod, but I think it should perform better than it does currently. I am currently running a 10" manual jack plate with 2" spacer blocks and a 23p Raker prop. I took the boat to Lawrenceburg Marine in TN, and they told me that the rings were "carboned up" and that I needed to run some Yamaha Ring Free through it and switch to Quicksilver Premium Plus oil to hopefully resolve the issue. I followed their advice as well as changing sparks plugs and installing new fuel lines from the tank to the carbs. In an act of desperation, I also added a hydro-foil but to no avail. Any advice would be greatly appreciated. If I left out any pertinent information please ask.
