3 types

In my 45 plus years of operating a sailboat with an inboard engine I have used both dripless and packing styles in 3 ways.

First is the packing style packed with "flax" type seals. These are a PIA as they do leak often albeit not much, They do require constant monitoring and adjustment.

Second, the packing style with the synthetic packing is a big plus over the above. It is a bit more difficult to get adjusted but once adjusted it offers many years of service with very little dripping as per Shawn. All that is required for the most part is monitoring just to be "sure".

Third is the dripless, it is not maintenance free as the water line for cooling must be checked often for flow as it is a small line and easily can plug up. Al's point of filtering is a good idea especially in silty conditions. It also requires annual lubricating under the bellows.

Point is no matter what you choose it will require "checking and maintenance" so if this is a problem I strongly suggest creating an access port for maintenance whatever you choose.

My seal does not have a water line and requires no routine maintenance at all. Not having a hose to either vent air or have water injected into it means the seal can trap air, so when the boat is hauled or after scuba diving that might get air up in it you need to burp it.

I survived that haul-out...

Had no room for dripless, so here's the traditional, with the precious split hub... easy to assemble myself, and fun with feeler gauges and more. But I had waited to long to notice the little "wobble" so it had time to grind away on the shaft log -- it had to be re-fiber-glassed (?). I pulled off the old stuffing box hose to see it was just about to open up a hole to the sea. Yikes. So get on it and submit you photo of shiny new drive train? Note I have no room to replace stuffing... I have to block the boat higher and pull it all apart ha ha to do that.
