I have dual 350 mercruisers on my 30 ft cruisers yacht. The tach is aligned on both engines at lower RPM's (less than 3000), but about 70% of the time above 3000 RPM the starboard engine races faster at the same throttle position. Is this just a problem with the throttle, or is there an underlying engine problem? <br /><br />Any advice is much appreciated.
