Re: Bilges - On vs. Automatic; Capacity?

One theory is that automatic pumps can actually sink a boat.
Let's say you have a stuffing box that starts to leak.
You don't notice and your automatic pump takes care of it for you.
This goes on for months and gets worse and worse.
You might notice that the battery seems a little down for one evening sail but don't think much of it.

You go away for a weekend. The leak gets much worse.
The pump goes on and stays on. The battery goes dead.
The boat sinks.

Some people solve this problem with a cycle counter others by having the lowest pump manual.
So every time you board the boat you know how much water it is taking on.
If it changes you know you have to investigate.

Just a thought, lots of people have fully automatic pumps and like it that way.
Everyone worries about different things.
