I just got a 1998 SunChaser with a 60HP Mercery Mariner bigfoot for free with a trailer. the boat is in excellent condition minus a few electrical connections that I have fixed but I can not figure out where the Tachometer hooks up into the engine. I know it sounds silly but Since I am new to "Boating" I am not able to figure out where the tach gets hooked up into the motor. Does anyone have an idea where I can get a Schematic of the engine so I can figure this out?
