It is a matter of choice. Packing is pretty resiliant stuff and long lasting (20+ years in freshwater) First, check the amount of travel left in the packing nuts. If there is lots, they will adjust up. I have had several boats out of the water for longer periods without difficulty. Packing is highly impregnated with wax. I have never heard of them drying up while out water.

I'm going to have to lean in Prowlerfish's favor on this one. My boat was out of the water for 2 yrs. Repacked the prop shafts before launching last year. By the end of the season, found rudder shafts leaking. In process of having them repacked now for this season. If nothing else, you have piece of mind bring the packing to a known state.

Also, if you have backing boards for the prop shaft strut bolts, check them. They may be under the engine(s), hard to spot, & you know how it goes-if it's not conveniently in sight, it's out of mind. If any rot, replace. Be sure to seal the area where the feet of the strut(s) mate with the hull-use something like 3M 5200.

How's your zincs? They may need attention also.
