Starboard tach started dancing
Starboard tach started dancing today. Heading through the marina at 1000rpm on both engines. After a while the starboard tach was reading 1600 rpm. The engines did not speed up. only the tach on the starboard side. She went down to 1000 a bit latter. As I exited the marina to open water I started to bump up the throttles. Both reading 1600 rpm. A few minutes latter the starboard jumped to read 2200 rpm but the engines did not. Bad Gauge? Ground condition?
