Hello all TIA for any help. I have a 2017 Mercury 115 4 stroke that seems to start surging or jumping after a few hours of use. The dealer has replaced the VST assembly and fuel demand valve but the problem is still happening. I have posted a video of the RPM jumping and the engine on youtube. Here are the links: https://youtu.be/IYJAKuZGQNU https://youtu.be/J44cdmcpwck
Again thanks for any help!
