Your clear and lucid insights to our head problems are much appreciated. Our normal reaction when confronted with head & odor problems is.... PANIC! You walk us through the issues with clear explanations and rational solutions. Are you secretly an engineer?
About 10 years ago, you recommended to me the SeaEra heads from Raritan - went with your recommendation and never regretted it (sold the boat - still had the wrappers on the seats).
