If you have looked at &#8220;experienced&#8221; exhaust systems, you will know that an exhaust this clean after almost 6000 hours is the exception rather than the rule.<\/p>\n<p><!--more-->The first photo is one of the flex couplings between the engine exhaust manifold and the exhaust dry riser.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"display: block; margin-left: auto; margin-right: auto;\" title=\"Wind-Horse-carbon-build-up-5700-hours-2.jpg\" src=\"https:\/\/setsail.com\/wp-content\/uploads\/2011\/10\/Wind-Horse-carbon-build-up-5700-hours-2.jpg\" alt=\"Wind Horse carbon build up 5700 hours 2\" width=\"504\" height=\"426\" border=\"0\" \/><\/p>\n<p>This is the exhaust manifold elbow for the port engine.

These elbows typically see the most most carbon build up, and in order to operate this cleanly:<\/p>\n<ul>\n<li>Engines must be run with sufficient load to burn fuel efficiently.<\/li>\n<li>They must not be overloaded.<\/li>\n<li>Back pressure has to be within correct limits.<\/li>\n<li>Inlet air volume must be sufficient.<\/li>\n<\/ul>\n<p>It is all part\u00a0 of having a quiet, efficient, ocean going yacht, with a long, happy life.<\/p>\n<p>Cory McMahon and crew replaced the motor mounts today, and made a few changes in the engine room as an experiment to reduce noise.
