Duramax prop shaft sealing system

[jack630]

Does anyone have experience or knowledge of the Duramax prop shaft seal? I'm considering replacing my standard packing seal with a dripless system and was doing some searches for information on dripless systems and ran across the Duramax. At least according to their literature, Duramax has corrected many of the problems with other dripless systems; however, there is almost no discussion about it on the forums or other sites. It looks like PSS dominates the market.
