We install quite a few las drops with the lip seal. Often replacing pss.
The hose is much nicer, though should still be replaced when the seal is serviced. Do spring the extra cash for the shaft mounted emergency
seal. If the seal fails, you can replace it in place, once.
The halves of it's housing act as the driver to seat it.
I'm not sure I'd want to try it in the water
, but I'd definitely do it with a quick lift
if needed. It's also paid off for two owners when we serviced them and found the seal required back ordered indefinitely, it provides the replacement in a location that is impossible to forget.
The other advantage is the housing for the spare seems to me to be able to act similarly to the clamp Maine
Sail uses to prevent shaft sliding out of the boat if something else fails.
