Dripless? / Temperatures
Have normal packing gland around shaft, packing replaced about 30 running hours ago. It has never dripped since repacking, either at rest or underway. I figured it would wear in a bit and start dripping, but after about 20 hours I loosened the nuts a little, but still no drip. There is, and always has been since I bought the boat about a year ago, a high-pitched, metallic whine (almost a "screeching" sound) coming from somewhere aft of the engine, but I cannot pin-point it (did not change after repacking). Lubricating water flow seems fine when I detach the hose. I just bought an infra-red temp gun and used it today after being underway for about an hour with 88 degree air temp, 2 ER blowers on, 82 degrees seawater temp. Crankcase temp 145 (dash water temp gauge read 180), Transmission temp 125, shaft temp 95 at stuffing box, stuffing box temp 90. Two questions 1) are these reasonable temps? and 2) should I worry about no drips into the bilge?
