A general "problem-found" note on an engine coolant pump problem we finally solved, for your edification - Perseverance has Cummins 855's on keel coolers (sealed system, no risk of taking in foreign matter), and the starboard engine began to randomly spike high temp alarms. We'd be underway for an hour or two, then all of a sudden the stbd temp would very suddenly spike. I discovered if I shut the engine down for even 5 minutes, I could usually re-start and run normally. Our mechanic was puzzled - we first replaced the thermostat, but the problem reappeared. We then replaced the water pump, and after doing so he reported that he could see no obvious reason - the impeller seemed firm on the shaft - so he asked me if I wanted to reinstall the old pump or keep the new one. Knowing my own "Admiral" would prefer safe to sorry I decided to keep the new pump, and the problem has not reappeared. It appears that a visual inspection of an impeller on the shaft may not always tell the whole story. On another topic, based on recommendations on this list, we purchased some Senco Home Model One battery-powered CO detectors before our summer trip, and I was very happy with this model. We mounted one in the unfinished master stateroom on the steel bulkhead it shares with the lazarette, which contains a night generator. We're somehow getting CO infiltration into the stateroom, and I found the LCD readout to be very sensitive and gave me quick response to both increases and decreases in the CO level. Now I've got to figure out where this stuff is getting through. FYI - we ran on inverters through the night, rather than this generator! Finally, we purchased a Little Jumbo 4-step folding ladder (http://www.ladders.com/jumbo1.html) based on recommendations on this list, and I have to say that the recommendation was accurate - it's the most solid and well-constructed folding ladder I've ever seen. It doesn't take much space when folded but is as solid as our steel boat when erected. I've sure appreciated the recommendations I've seen and the knowledge I've gained while following this list. I wouldn't even have known about the CO problem if I hadn't been motivated to get a detector in there by one of the discussion strings here. To coin a really corny slogan, "it's nifty to be a listee!". Jeff Patton Perseverance Seattle
