I have had this 135 hp evinrude outboard for over 30 years Last saw the water about 20 years ago. I have had it worked on by a "professional" boat mechanic... and have been gouged for several hundred dollars each time. I have started it every spring and the motor has always started fine. This past week I attempted to start it and it doeswn't seem to be firing. I have read in these forums that there is a kill switch... where would i find it. And how about the power packs ..how would I test them to see if they are ok ? any advise would be appreciated.
