23' ChrisCraft Chevy350 originally in Volvo penta setup, now in merc Alpha 1 setup. <br /><br />In this picture there is a wire to what I think is a water temperature sender (at 6:00). Also in the picture at 3:00 are prongs from a sender attached to the top of the engine water pump. Is that for a warning buzzer or is there supposed to be a water temp guage attached to that?<br /> http://i23.photobucket.com/albums/b365/rebars1/9529635d.jpg <br /><br />Sorry for all the questions, I'll be getting manals as soon as I figure out what year the engine is. (I'm used to Ford 302's)
