Does it idle OK in neutral? and die when it's put into gear? The simple fix to try is to indeed raise the idle speed until that no longer happens.
However, if you're using excessive fuel, that, coupled with your other symptoms (ie slowish motoring speed) may mean your prop is too big a pitch as well.
