I would suggest plugging the hose connector with a wine cork to keep unwanted irritating noise from flowing down the tube. For maximum sound reduction, consider giving her the full bottle of wine after removing the cork. According to Dr. Spock bottlefeeding is usually helpful for preventing crying and whining. **Q: Is it safe run your motor for about 20 mins at a low speed.** A: Not sure about that. I never do it that long, but I don’t see why not. It does a great job of providing the water supply needed **Q: are the muffs rubber or plastic?** A: The muffs are rubber. **Q: Will it work for a 2003 Yamaha 225 4 stroke?** A: it fits a bravo outdrive , so I don't see why it wouldn't fit. ## Frequently Bought Together - Redneck Convent Dual Water Feed Boat Motor Flusher Rectangular Cup Muffs with Hose Fittings Flush Kit – Marine Outboard Engine Flushing - Slippery Pete - Lower Unit Gear Oil Pump for Standard Quart Bottles, Includes 3/8 inch Metal Swivel, 8mm and 10mm Adapters Fit Most Marine Boat Outboard Motors (NOT COMPATIBLE WITH VOLVO PENTA) - Quicksilver 858064Q01 High Performance SAE 90 Gear Lube for Mercury Outboards and MerCruiser Sterndrives, 32 oz --- ## 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.uk/products/51821867-dual-water-feed-boat-motor-flusher-rectangular-cup-muffs-hose](https://www.desertcart.co.uk/products/51821867-dual-water-feed-boat-motor-flusher-rectangular-cup-muffs-hose) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
