a Big Pump
Bought a 3700 gph Rule pump for the Tolman just in case I take a lot
of water. My normal bilge pump is a 750 gph one. I intend to find some smooth bore hose for it and some oversized wire to power it. Downside is, it was expensive and I will probably never use it. Might even get a dedicated battery for it. |

Make sure you put that battery in the lowest part of your boat. -- Birther-Deather-Tenther-Teabagger: Idiots All |

Wow, to me that's a bit of overkill, but if need be uyou could probably use it for jet propulsion if necessary. ?;^ Q |

I was looking at a sailing magazine a couple of months ago. I saw an article about someone connecting a hose to the water pump, then using the engine to suck water out of the boat. Seems like that would cut out a lot of the battery problems because it would engine not battery doing the work. -- Nom=de=Plume |

Caveat: If the pump sucks all the water out and burns up, you have lost the use of your engine. The bypass valve must be manned constantly to avoid that calamity. |

I think that's a good plan, with a couple of caveats: It's a good idea to derate the capacity of bilge pumps by 50% or so to compensate for head loss and hose friction. It's also important to remember that bilge pump float-switches have a proven record of unreliability, leading to the need for a manual override switch, and possibly the desirability of a second, totally separate, pump/float-switch combo. No one has ever complained about having too much bilge pump capacity. If the cockpit of an open boat swamps with big water you are only seconds from a loss of stability and capsize. |

You should only have to match the wire guage of the leads on your pump for your wiring. -- Posted via NewsDemon.com - Premium Uncensored Newsgroup Service -------http://www.NewsDemon.com------ Unlimited Access, Anonymous Accounts, Uncensored Broadband Access |

My reason for getting this pump is reading David Pascoes advice on the topic. |
