On our last trip out sailing on Encore I noticed the Volvo was running hotter than it should be. My first thought was a lack of cooling water flowing in through the new smaller strainer, but then it was possible the coolant was low — I added about a quart. After returning home I also wondered if the temperature gauge was reading correction and decided that next trip down to check a few things.
Enter the digital thermometer. I’ve never had one of these gadgets and now that I do, can’t believe it has taken me so long to buy one. I picked up a "well made" rubberized refurbished cheapy for $12 (including free Prime shipping) on Amazon and can’t believe just how super is it. The range is from -30C to +360C and it has a soft switch for either C or F degrees. There is also a backlight (on or off) and a surrounding air temperature or laser option. Amazingly simple to use and nearly instant reading … with a hold feature as soon as the trigger is released. If you do not have one of these, get one!
Now to see if it can help me diagnose why the auxiliary diesel on the boat is overheating.
