Bilge pumps

[Razorbill RIBs]

Am planning to fit several bilge pumps in the Pacific.....

Will be fitting an auto (Rule 500gph) in the main bilge beneath the prop shaft /in front of the Jet.....for when its on mooring etc.

Have a Rule 1000gph which I'm planning to fit aft of the Yanmar in the engine compartment......there is a lowish bulkhead between this compartment and the main bilge with 'run throughs', but my logic is better to have it there than not, in case run throughs should ever block etc. Need to fit a main (pair of?) big pump(s) in the main bilge also......

What heavy duty high gph pumps do others with inboards use? Rule like this /pair of? RULE 2000 SUBMERSIBLE BILGE PUMP - CHEAPEST ON EBAY | eBay

There are others less than half the price....unless anyone knows different I suspect its better to go for the known brand?

I read somewhere that the china one have smaller motors and burn out. You pay for quality but get a lot better result longterm

A friend fitted a cheap one on his fishing boat and its life could be counted in mintutes, cheap crap.
Rule or johnson seem to get the thumbs up....

The Rule 2000 is the most widely used electric submersible pump for boats. I'd certainly be happier with Rule than the more obscure types.

I'm sure you realise that the capacity rating is in US gallons, open flow and with a fully charged battery. Experience tells me that a Rule 2000 will actually do about 800 gph in real life.

I wrote an article on bilge pump system design which may be of interest: http://www.saltyjohn.co.uk/resources...tem_design.pdf

Then again, it may be of no interest at all!

Chewy / Biffer....cheers both, will be going for the Rule......it's the West Walian in me which makes me look at cheap(er) things

Salty.....that was of interest.....thank you......Hadn't really thought of the losses in performance tbh

A pair of 2000gph it is then.....no shortage of space.... Have a manual whale type also hard fitted in the ali box aft of the seats on the Pac. When teh met owned it it had a salvage pump fitted also (for casualty boats I guess)....sadly no longer there

Thanks all

I can't see that lasting long on a RIB, they're not much good on dry land pumping fresh water. Been there, done that, cursed it,kicked it

The RNLI use more of less the same design but a Honda one, ours has never given us any trouble.
Obviously you don't leave it open to the elements, it needs to be stored correctly like everything else.

I bought some Attawood's from Walmarts in the States a few years ago. Been as good as gold and was cheap as chips too at about $15 for a 1200 lph one. The other one was a fully automatic for just under $30 that I sold on for a profit.

My little bro lives in Boston.....I'm sure he gets fed up with sending me bits and bobs, but.....we really do get stiffed on so much boaty stuff over here!!......He's sent me Keel guard, Opti plugs and a whole host more for SO much less (inc postage) than we pay over here
