I am going to replace the throttle cables on my MerControl and I am wondering if I should just order new ones from my closest merc dealer or if there are cheaper aftermarket cables I can purchase? I am also going to replace the hydraulic hoses on the power trim unit and the wiring harness that plugs into the motor, what are some of your valuable opinions on replacing these? <br />I am also going to add a tach. to the motor, will a standard tach be sufficiant? What is the red line on this old 115hp inline 6?<br />I live in Kitchener Ont. Canada.<br />Any and all advice is greatly appreciated!<br />Sincerely Jon
