    It's funny you say that, I work for Australian Army Marine and we see a lot of outboards with the same issue as you are having and 9/10 it's the VST, which holds the high pressure fuel pump. If that pump is starting to fail then you won't be able to achieve those higher rpms

    Do you drain the vapour separator and if so how often, but if not have you ever drained it. You must do it weekly if you're using it frequently.
