I have got Mariner 75hp 4-stroke 2002 built. There are no manual for connecting the instruments: tachometer, oil pressure gauge, trim gauge. Maybe somebody knows were I could obtain some technical literature with pictures or any drawings for that? Does tachometer need separate cable? Does oil gauge need sending unit, or it is preinstalled? Where trim sender is positioned? What for there is closed hose with small diameter (two hoses protruding from cover - fuel and unknown with smaller diameter)?
