Ok, I have read all the posts pertaining to starting problems on this unit, still having no luck. <br />A little history first.<br /><br />Boat went in water and both engines started without problem, boat had been winterized and readied for water properly. <br /><br />Found the starboard engine would not rev past 3,000 rpms but ran fine below that mark.<br /><br />Brought in to get service. and this is the start.<br /><br />NO Spark - turns over without problem but no spark<br /><br />Done so far:<br /><br />New points and coil<br />Timing<br />New iginition<br />Have done the insulated screwdriver trick to check for spark and getting spark.<br /><br />WHAT NEXT! <br />PS - anyone in the GTA area in Toronto interested in a paid marina visit to help diagnose and repair (with compensation of course) let me know<br /><br />mark@tech-know.com<br /><br />Edit note: Mark. you can edit your post by clicking on the EDIT icon. I fixed your topic for you. JB

SO you do get spark when using the srew drive? If you do replace the plugs and wires. If not pull the lead from the coil to the cap and check for spark. If you have spark here replace cap and rotor. The problem has to be somewhere in this area! Let me know more.
