FREEZING CLIMATE USER
The Flush-M has a 'punch' out sacrificial seal in the center of the cap. If the launch or yatch outboard engine is operated or winterized in freezing locations, it is recommended that this seal be removed.
INSTALLATION STEPS
1. Lift the Flush-M cap off of the flush port & lay the base of the cap on a flat work surface.
2. Insert the appropriately sized center-punch tool into the vent hole located at the center of the cap until it is resting on the sacrificial seal.
3. Using a mallet, lightly strike the center-punch tool, breaking free the sacrificial seal.
GUIDE FOR MERCURY INSTALLATION
1. Remove the original OEM plug from the engine cowling.
2. Unscrew the OEM plug from the 3/4" female hose receptacle.
3. Separate the OEM plug from the lanyard by rotating it in a counterclockwise rotation until free.
4. Fit the Flush-M Mercury Flush Kit to the lanyard & the ¾" female hose receptacle.
5. Install the Flush-M Mercury Flush Kit back into the engine cowling, securing it in place with a ¼ turn in a clockwise rotation.
6. If required, use a wrench on the male quick-connect collar for added leverage. Do not overtighten past ¼ turn.
Your boat or ship engine is now ready to be operated or flushed. To flush, simply remove the flushing cap & attach a hose to the Flush-MTM utilizing the included quick connector. Refit the cap upon completion.
RED QUICK CONNECT

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $30 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Flush-M products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
