I think I would trust a rolling ball mechanical float switch more than an electronically controlled one. If the leakage into boat was regular and constant it would make sense to put a pump on a daily timer routine as well as have the float switch pump. I'd fix the leak.

I was thinking of those (usually wooden) boats which habitually take on water. There arrr plenty of them about and yes fixing the leak would be sensible but people don't always do that !

To comply with the euro Regs for our barge we had to fit 2 float switches one at normal level and one a bit higher wired to a panel in the wheelhouse. Idea being if the low one failed hopefully the higher one wouldn’t. Had a pump in the fore end which tested the level every 2 mins for a second or so and kept running if there was enough water inside it. Can’t Remember the make but came from ASAP.

In case one breaks, which on the good ship Ellis, will happen. grrr - as it happens I already have a spare manual one "somewhere" and a mains powered float switch hippo thing for if things got REALLY desperate!

That looks a bit bulky to fit where it needs to but I suppose I could alter the drip tray under the stern gland to accommodate it - I don't get much (if any) through the prop shaft... just rainwater from the rear lockers when they get clogged up... which is too often I admit.

Bulky seems an odd word as they are very small but I suppose lengthwise it could be awkward.

The best bilge pump is the Whale supersub. The auto version is about £50 which is NOT cheap but it is a very very good unit. Good design and the motor is on a simple bayonet type fitting so takes seconds to take off to clear any shite off the impeller. I was told by a man who tested dozens of pumps for PBO magazine that the Whale supersub is the best one, a conclusion I had already come to despite not having tested many. They also have a joker valve in the outlet as standard (non return valve) which is a good feature of course . A good way to mount them is by fixing a strong magnet to the base and clipping it down with that go keep it in place yet still moveable. that's on steel boats obviously. This is definitely not correct
the best bilge pump in the world is a frightened man and a bucket

I'm now thinking, shall I leave the existing one in and put an auto one along side - with a "y" connector on the exit pipe with non- return valve to both pumps.... so use the existing hole to save drilling another exit
am I overthinking this? -

Got a super sub fitted on our boat. It's not sunk yet.

You'll be ok Jim, you have a big fat buoyancy aid on the top to keep it from sinking.
