Hurricane Earl, was forecast to most likely stay offshore, but provide a glancing blow to the area. The paranoia began around Monday when forecasters could not tell how close it would come, but we could get winds up to 75mph sustained. It was all that anyone talked about, and all over the news and weather programs. Hysteria was building, and it was hard not to get caught up in it.Boat US is our insurance carrier for the boat, and their policy is to pay for half the haul, wash, and blocking, so I decided to play it safe, and as a bonus get to do some needed work to the bottom of the boat.
The next project was to paint the prop and shaft with Cold Galvanising as it was too popular with the barnacles. We had nothing on there up to now.
The boat came out on Thurs the 2nd Sept, and went back in on the Tuesday after the Labor Day weekend holiday.
Opening the seized stuffing box was a bugger, and when I tried it on the water last year, I think I loosened the seal to the stern tube. That is why I wanted the boat out of the water this time.
Anyway, replaced with 3 pieces of square shaped PTFE flax stuffing ($5 a ft). 5/16ths is the size, and the 3 pieces fit in perfectly. Each piece was over 4" long to go around the 7/8ths shaft (so get more than a foot of the stuff).
The stuffing box and locking nut were frozen together. Used PB Blaster overnight and 2 big pipe wrenches to force them apart.
Did have a drip every 6 seconds (with engine off) before, but a nice dry bilge now (1 drip every 20 seconds when under power).
Can get the packing nut tight enough by hand - no wrench needed there. Make sure to use wrenches to tighten the locking nut though, as it will work loose otherwise.
Got the rudder and a foot of the waterline twice with a quart of paint (400 sq ft coverage), plus we touched up around the top of the keel. Let the bottom coat dry overnight before applying the second coat. Used the roll and tip method, and got a very smooth finish.
The cold galvanizing was easy enough, and we also hit all the metal thru hulls with the stuff. Used a full aerosol can on the project, and the can cost around $8 at Do It Center.
