2001 200 optimax
serial number ot 273182
I've read that getting the optimax up to the right temp. before getting up on plane is very important. What are those of us who have the older optimax with no capability of smartcraft or other temperature capabilities from the factory do. Or maybe there is a harness and i just dont know where or how to find it. I've heard that i can install a analog gauge by drilling and threading a temp. sending unit into the motor then wiring a gauge to the dash, but i am not sure that is wise for some of us to attempt and the end result is fair at best. I am wondering why if mercury considers this as all important they did not include something on the motor and or a harness that something could be plugged into later. For those of you that feel i am basing mercury motors you are wrong! i am trying to do right by my motor and to follow the advise of others on the forum and i am open to any suggestions. Should i just guess at my idle time before heading out and hope it is right? am i to just wait for a temp alarm to go off? what if a themo is stuck open or ... thanks
