I just repacked the packing nut on my 2005 Supra launch 21V. I used three bands of 3/16" packing. (of course took out the old packing) It went great. I adjusted it at the lake and get a few drips per minute. A few more in reverse but no big deal. We wet out for a few hours and it ran great.
On my next trip to the lake I put the boat in the water and as paranoid as I am I checked the nut, and it was dripping a again few drips per minute. Perfect. We have about a 10-15 minute boat ride to our camp site so we headed up at about 35-45MPH for about 15-20 minutes. Good long constant ride. I decided to check the packing nut when we got to our camp site and it looked fine but I put my hand on the packing nut and the prpeller shaft and it was pretty hot to the touch. I thought the water should be cooling this?? Is this normal? I decided to back of the nut another half turn and got the drip up to about 5-6 per minute. Am I paranoid? Am I missing something? Whats the normal temp of this packing nut and shaft around this area? Is there anything I should check?
Thanks
