Hi, I recently purchased a 2000 glastron with a 2001 90hp johnson ocean pro that seems to run great, but while running today all of my dummy lights would blink on and off every 30 seconds or so. These lights include low oil, check engine, temperature and no oil. I could slow to an idle and then run again and they wouldn't come in for awhile.Not sure if it's an electrical problem or something serious. Thank for any replies
