We are about to become the proud owners of a 2019 C28. When we bring the boat home, we want to travel with basic tools, one of which would be a proper sized wrench to adjust the shaft packing. Can anyone tell us the size of the nuts so we can purchase the correct spanner wrench?
 
The wrench of choice is the Ridgid E-110 offset hex wrench. I use one like this from Amazon, works great for our boat. You need two.

Thank you for your reply and Amazon link.

That's the one. Also known as a gland wrench. It's also a good idea to have a conventional pipe wrench aboard.
