The sending unit on my 1994 200HP Merc is broken and I need to install a new one. I've got the new one on order. My questions are: 1) What position should the motor be in when I install the new one?
2) When I adjust the sending unit to match the gauge, which position is best to have the engine, all the way up or dn.
