Hi, I have a 98 25hp johnson outboard that has been having a little trouble starting lately and I was wondering if anyone could help me figure out what is wrong with it. When I get to the lake it always starts right up, but maybe one time in five after that it just won't start at all. It typically happens when I drive for 15 minutes to a spot then fish for 30-45 minutes and then try to start it. It has also stopped running when accelerating and slowing down on a couple occasions. Thanks in advance for any advise.
