Yeah, but the issue with a traditional wax packing gland is that if you do have to replace it you're going to pay through the nose for the labor. If someone with a Super Air has a chance, take a picture of the prop shaft where it exits the hull. There is almost no room to get a decent sized wrench in there.
I promise you a traditional packing gland will require a lot more work than a dripless setup.
Like I said, on a v-drive I would spend the money no questions asked (especially if you do your own service, you don't want to deal with adjusting a traditional setup). On a direct drive I would put it further down on the list, but if you have the money, I would still get it.
Dave, Malibu didn't add it as an option until late last year, and it's still not on the 'books'.
Here is more info.
