"Warm" to the touch, Okay.......
"Hot" to the the touch, not okay.
If you put your hand on the nut/shaft after it has been running for few minutes and it is a little warm to the touch, you should be okay. Hot to the touch, as in you can't leave your hand on it or your brain response is "That is hot", then it's too hot. IR Thermometer is a good thing to actually measure the gland, start with the hand thing first to get an idea.
Bear in mind that ocean/lake/river water is cooling the gland and if the water is warm, the nut will be warm, not matter how well the shaft it being cooled. My mom and dad lived on the Cheasapeake and I remember in August, the water could be 83degF in so of the shallower areas. I lot different where I live, where the water doesn't get more tha n 70 deg F and more times than not <65 deg F.
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
