PSS VS OJprop Dripless shaft seals

[captainmas]

Hello Capts,

We have been restoring a 76' 28 Bertram. We just had a new 260 gal alum tank made, real nice but it makes it tougher to get to the shafts to repack, so we decided after much research to go dripless. The question is which system is better PSS or OJ?

Any help would be appreciated.

Thanks Capt Mas
