I just bought a used Catalina 36 MkII. I’m thrilled with the boat but I have an issue that came up during the survey that I’d like to resolve. The tachometer appears to read high. The boat idles at the proper speed, but the tachometer reads more than 1,000 rpm. A similar problem occurs at cruising speed as well. I discussed it with the surveyor and he suggested it was related to the alternator. What’s the issue here and how do I fix it?
