Comes with an in-line filter and pumps water great to use as spraying the inside of the boat down! ### ⭐⭐⭐⭐⭐ Review *by A***R on 8 September 2025* Good pump ### ⭐⭐⭐⭐ Review *by K***O on 26 July 2025* Pump Does the trick, needed something to wash down the pontoon boat floor to cool it down for the dog and myself if it gets too warm. I mounted it into an old RV battery case onto a 1” thick piece of wood and attached it to the inside of the side wall with wing nuts . I also added an 2 pin rocker switch to the case and extended the wiring to reach a leisure battery we use for Life well pump, lights etc under the console. A little in line 15amp fuse close to the battery and it works a treat. You will need to buy a hose long enough to reach the water source. Our hose was floating on the water surface so I attached a small fishing weight with a cable tie to the end. Just heavy enough to submerge the hose but not too heavy to pull it down too much.- ## Frequently Bought Together - SEAFLO 33 Series Washdown Deck Wash Pump Kit - 12V DC, 3.0 GPM, 70 PSI, Heavy Duty Pressure Switch, for RV, Boat, Marine, Yacht, Freshwater, and Saltwater Applications | 4-Year Warranty - 1/2" ID x 3/4" OD - 10 Ft High Pressure Braided Clear PVC Vinyl Tubing Flexible Vinyl Tube, Heavy Duty Reinforced Vinyl Hose Tubing, BPA Free and Non Toxic - Sea-Dog Washdown Water Outlet - 316 Stainless Steel --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/323728785-33-series-washdown-deck-wash-pump-kit-12v-70-psi](https://www.desertcart.co.th/products/323728785-33-series-washdown-deck-wash-pump-kit-12v-70-psi) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-27*
