Several years ago, I purchased a 1985 Cat 30, with the Universal M25 diesel. The alternator was weak when I got it and shortly afterward it died altogether. I had it rebuilt at a local automotive alternator and starter repair shop and it seems to be working just fine. The tach only indicates a max RPM of about 2100 unloaded, and 2000 loaded. 2k will move Serenity along at about 6 knots (gps measured), but the engine sounds wound up tight. The question is: am I getting a correct reading off the tach?
