Mariner 20 ignition problem


Aug 24, 2009
have a 1997(we think) 20 hp Mariner long shaft on our party boat. While just putting around one day it stopped like the kill switch was pulled, cranking it , it spun as per usual but no go. Towed it home, later it started. Couple days laterit ran for about 40 minutes, turned it off , went back an hour later no go. Left it over nite, started a couple times no problem. Later in the day no go. Still won't start, as in no spark. All the kill switch, neutral and ignition switches chech fine. Another thread suggests could be magnets loose? How to check?, how to tighten if that is the
