Moves a lot of water! Review: 800 pump functionality is great; FYI: Be careful buying the 1200! - EDIT UPDATE 2016-12-02: Used the pump for one full season now. For me, that's about 28 days out fishing in that boat, using the pump. Pump is still working strongly, smoothly, and quietly. Can't guarantee it's pumping 800GPH, but it pumps a lot of water pretty quickly! Could be 800GPH; no reason to think it isn't. I would guesstimate the pump ran about 50 hours of actual pumping. Most of that is in 1 minute bursts every 3-5 minutes. On one particular trip, the pump runs full time for 1-2 hours at a pop, about 3-4 times on the trip. The *REST* of the time it runs day and night on 'intermittent' mode, about one minute spray every 5 minutes, because we're keeping large live bait in the livewell for catfishing. And like I said, it's still running strong and quiet. ----------------------------------------------------------------------------------------------------------------------------- INITIAL REVIEW (made immediately after purchase as a 'buyer beware' type thing): The reason I am writing a review so soon after purchase is to possibly help someone else avoid the issue I had. I waffled back and forth between the 800GPH and the 1200GPH model. I had both in my cart, and decided what the heck... I went with the 1200. BUT what I didn't realize was that the input and output sizes CHANGED from 3/4" on the 500 and 800, to 1 1/8" on the 1200. On discovering the problem (with my head down in the bilge area of my boat failing to get the pump intake pipe thru the transom), I crawled out and went back to the desertcart page where I ordered it and DID see a little bullet item at the top when the 1200 was selected, saying that it was 1 1/8". So it was my own fault, but I'm guessing other folks might not notice like I didn't, OR might not REALLY realize what that means... Most aluminum boats under 22' have 3/4" diameter input/output livewell pump fittings. So if you buy the 1200, you have some serious work to do to make it usable, including drilling the current 3/4" transom hole out to 1 1/8" (which is likely to be difficult). Also the 3/4" hose going to the livewell sprayer won't fit on the pump output. So you'll need to replace that hose, or get a 'converter' to take the pump output down from 1 1/8" to 3/4", which will restrict the pump output, and might stress the pump. ## Features - Pump with innovative engineering and compact design provides the most reliable aeration in contained spaces such as livewell - Powerful, reliable pump is rated for 800 gallons per hour (gph) output at design voltage 13.6 volts DC, or 750 gph at nominal voltage of 12 volts DC - Features the most advanced materials, including premium-quality bearings and state-of-the-art brushes, alloys, and magnets - Patented shaft seal prevents leaks caused by misalignment, caulked and tinned wiring eliminates wicking, prevents water damage, and resists corrosion - Motor cartridge locks for secure placement, and unlocks for easy cleaning, maintenance, and replacement - Has a ¾-inch diameter, 3 ½-inch-long inlet, and a threaded ¾-inch interior diameter outlet - 12-volt pump connected with 29-inch wire - Pumps fresh, oxygen-rich water to livewells and baitwells - Uses less power for long pump and battery life - Cooler-running motors, premium materials, watertight seals and waterproof wiring - Cartridges are replaceable and interchangeable between bilge and aerator pumps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001O0D6KQ | | Best Sellers Rank | #8,552 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #3 in Boat Bilge Pumps | | Brand | attwood | | Brand Name | attwood | | Color | White | | Customer Reviews | 4.7 4.7 out of 5 stars (3,143) | | Date First Available | October 1, 2001 | | Global Trade Identification Number | 00022697465078 | | Included Components | End Product & Information | | Item Dimensions LxWxH | 6.56 x 10.69 x 9.38 inches | | Item Package Dimensions L x W x H | 9.72 x 7.09 x 3.58 inches | | Item Weight | 14.1 Ounces | | Manufacturer | Attwood | | Maximum Flow Rate | 13.33 Gallons Per Minute | | Maximum Lifting Height | 3.3 Feet | | Model Name | Attwood Boating Bilge Pumps | | Number of Items | 1 | | Package Weight | 0.5 Kilograms | | Part Number | 4650-7 | | Power Source | Battery Powered | | Product Dimensions | 6.56"L x 10.69"W x 9.38"H | | Size | One size | | Sport Type | Boating | | Style | T800 | | Suggested Users | Unisex-Adult | | UPC | 022697465078 | | Voltage | 13.6 Volts | ## Product Details - **Brand:** attwood - **Color:** White - **Global Trade Identification Number:** 00022697465078 - **Item Weight:** 14.1 Ounces - **Maximum Flow Rate:** 13.33 Gallons Per Minute - **Maximum Lifting Height:** 3.3 Feet - **Power Source:** Battery Powered - **Product Dimensions:** 6.56"L x 10.69"W x 9.38"H - **Style:** T800 - **Voltage:** 13.6 Volts ## Images ![Tsunami Aerator Pump - Image 1](https://m.media-amazon.com/images/I/71OtCDo7bVL.jpg) ## Available Options This product comes in different **Pattern, Size, Style** options. ## Questions & Answers **Q: Are these pump submersible?** A: I don’t think submerging this pump is recommended. I checked the installation instructions that came with my aerator 800 gph pump and all of them show non-submerged mounting. There is an application for recirculating water in a live well mounting the pump directly thru the side (with the pump on the outside of the live well) with a intake screen near the bottom and a spray head above the water line. **Q: This pump can be used inside tank** A: I have one for my bilge which does get submerged and one for my live well that is in the same area. So it gets submerged also. So they do operate under water. I haven’t used them inside a tank but I think they should work. **Q: will this pump run in reverse as well to drain my live well** A: No our Tsunami pumps are not designed to run in reverse. **Q: Can you plum one of the fittings with a filter?** A: We do not recommend use filters on the outlets. We do offer strainers for the inlet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality piece *by R***R on November 16, 2025* Works very well!
