Re: 1971 60 hp evinrude 3 cy no spark
If I could add....you will need a top notch battery for this particular system and ensure it's fully charged all the time. Any voltage from the battery below 11volts could blow the amplifier....very expensive.
If you find that you need points, they are no longer available from BRP or in most cases, from any aftermarket company. However, you can search up SeaWay Marine in Washington State and get them. Ask for the factory seconds. Yes, I said the "factory seconds". There is nothing wrong with them except maybe the points may not be exactly square. New top shelf points will run around $65 where the seconds will run around $32. PN is 383655.
Many times the old points can be poished and used. I've had success using 600grit paper. Make them shine.
