New to me boat, 3 days after purchase smartcraft guage gave me STBD system fault 19 Catalyst. Catalyst is not working properly. Emission control problem. In talking with mechanic he said something is funky with starboard O2 sensor. Could be sensor, could be a wire. Is there an on line manual with codes and potential cause of the system error? Hoping it isn't the CAT, mechanic said sensor, would CAT throw a different code than 19? Anyone else have similar issue in past? thanks in advance if anyone has had same or similar issue.
