I am tring to istall a temp guage on my merc 150 (2003)and am confused as to where the sending unit goes. I believe that it is threaded directly on to the head port side but the units diagram shows it actually penetrating the block. Am I correct in assuming that the unit just screws in metal to metal??? Thanks for any help
