Ok so I have an intermittent check engine light. After doing some reading I learned with my boat being a 2001 I can do the "paper clip" test to check the engine codes stored resulting in the check engine light coming on. When I did the test my check engine light flashed one solid flash, a pause, followed by two quick flashes. To my knowledge, this means code 12. From what I have researched, a code 12 is just telling me that the boat is in "service mode".
I am having some issues figuring out why I am getting this light. The boat runs very well (put 8 hours on it this weekend) but the check engine light flashes faintly every once and a while. Sometimes it will stay on, sometimes it will not. Does anyone have any ideas on how I can figure out this bug?
