Thanks for all the advice. This is a great resource (thanks Stu). I've
read some of this info scanning different online sites - but this list
gives quick feedback on how and why.
That Whale sub pump is exactly the one I was looking at. Plus a switch.
I will take the wiring advice - heat shrink and silicone etc.
Any thoughts on the discharge?
I've read some people discharge through the galley sink drain - which
would keep the hose run short and easy --- but then I'd have to leave
that seacock open..
The other option is to Y the discharge to the current manual pump
discharge (or one of the above waterline cockpit drain hoses) - but that
would need 18'+ of hose.

Dennis had a good call with heat shrink and painting with liquid

than the connection, and injected marine silicone inside with a
syringe. When the shrunk, silicone gushed out the ends. It has been
wet often.
Maybe I'm just lucky, but my 12 year old Rule pumps and float switches
are still doing fine. I have a little 500 as the primary pump, and a
big one that stays up on a platform about six inches off the bilge,
just in case. The 500 does get clogged up with bilge gunk, and I just
replaced it because they can't be taken apart and cleaned out. One
thing I do is take a garden hose to 3/4" adapter and flush the hose
out with high pressure dock water. I'll also backflush the pump with
the garden hose.
Most of the float switches I've seen fail are really due to bad
wiring. I've seen plain crimp connections just sitting in the bilge,
and it's no wonder the wire rots out. The worst, if you can believe
it, was just wires twisted together and covered with electrical tape.
No kidding. I found that down here in Mexico, as the sport fishing
boat was sinking at the dock. The guy came back to town, and when I
told him that I'd saved his boat he didn't even say thanks. Power
boaters. (It probably didn't help that I said whoever did the wiring
ought to be taken out and shot.)

I ran a rule float switch to one which failed that first year.
