    I recently wanted to add an emergency pump and looked at this type of gas powered pump but decided to go with a Rule Evacuator pump. It pumps 7700 GPH which is not far off from the honda powered pump. I will run a set of accessible leads from my main batteries for easy deployment. It seems maybe easier because you dont need to worry about gas, running it regularly, it is smaller and yet has very similar pumping capabilities. My batteries are pretty high up in the engine room and wont be easily flooded.

    Instead of us guessing, what exactly are you trying to do?
    Please include liquid, lift and real length of hose.
    How many GPH do you need?

    Capt Ralph, I interpreted his question as he wants to have an emergency high volume dewatering capability on board. Many people want to have this capability. My question to you is yes having a gas powered pump like the Honda unit is nice, but it is cumbersome and needs to be stored and periodically operated. What is your opinion of the type of Evacuator pump sold by Rule. It is electric, but is 7700 GPH in combination with a couple of installed 2000 GPH bilge pumps is maybe a simpler, but still useful approach?

    2002, I was working SeaTow KB.
    We had Honda and Wisconsin powered gas trash pumps.
    They started reliably and with proper priming, would move rated water.

    We learned the hard way about gas engines CO emissions.
    While pumping out, trying to find and stop the hulls water ingress, the exhaust would start to fill the boat while were snorkeling about in.
    Not good for trying to work while sucking in CO.

    We worked around our salvage issues and used gas pumps only when conditions were safe later on.

    I sold (gave aweigh) my last gas trash pump from our company 10 years ago.

    I have no positive comments about gas powered pumps to offer.

    If you are trying to save your self with no other support around, you need manually implemented, belt driven pumps off of your main(s) engines.
    There are many options available.
    We currently have a manual implemented crash pump on out stb main that starts at 160GPM at idle speed, AND the main engines raw water pumps to de-water tyhe engine room directly if needed.
    Naw, I don't think were sinking from much.

    I went with this for my emergency dewatering. Available at Sunbelt and United rental stores for purchase. I have crash pumps on the engines and will of course use if it comes to it but I don’t like the idea of using the engine raw water pump because of the potential to run dry and take that engine out of service. Gas pumps can be difficult to prime and as mentioned with todays gas one has to periodically run to make sure it is available when you need it.

    They can run a battery down REALLY fast. So keep that in mind. There is no 1 great solution. I think the solution is several different types of pumps.
