Bilge Pump

[jon_bailey]

The bilge pump in the bottom of my Sportsboat stopped working at the weekend. Removed and it is knackered.

I thought that it was an automatic unit with manual over-ride at the helm but on removing it, it only has two leads going to it that I assume are simply a switched positive (from the helm) and earth, so how can this be automatic?

This leaves the following questions:

1) Do I need an automatic or will a simple manual unit be ok? I have never had a problem with any water ingress on my boat but realise there is always a first time.

2) If I fit an automatic (connected directly to the battery) do I need a manual over-ride at the helm?

3) What size do you recommend for a 21' sportsboat?

I realise that it is a bit sad to be talking bilge pumps after such a great weekend but it needs to be fixed. Thanks.

Most boats have a bilge pump and seperate float switch. I fitted a new switch tother week. Best to wire it through an override switch but is OK without.
I'd fit one that fits the pipe that you already got.

Jon,

Some pumps actually incorporate a float switch in the pump housing Others use impeller resistance (no float switch)- If water is detected, the pump will continue to run until all the water is removed. If water is not detected, the pump will turn off. It runs up for a second or two every few minutes to see if there is any resistance.

Do you need a telephone number for the prop repairers? /forums/images/icons/wink.gif

I am afraid that I already have plenty of expertise with prop repairers.

Just remember that those in glass house should not throw stones /forums/images/icons/wink.gif.

Fit two - one auto ( I like the impellor sensed type) and another operated from the console.

I find the float switch type to be less useful as in a largeish bilge it needs a lot of water before it activates (6 large buckets)

We have a weeping stern gland - doesn't drop a lot, maybe a pint or two a week, but it is very reassuring to hear the thing whir then cut out.

Add the manual pump becuase if you ever really need to get water out of the boat, the faster you can get it done the better.

Yes, definitely have a manual pump too. You'll be glad of it if your electric one packs up just when you need it most.
