Buying Guide
What size should I choose?
Consider your engine horsepower and the size of your vessel. Larger engines generally benefit from bigger bags with higher water capacity to ensure thorough flushing. If you frequently service dual‑prop sterndrives, look for bags with broad dimensions and robust PVC construction.
What features matter most?
- Capacity: Higher gallons allow longer, more complete flush cycles.
- Ports and plugs: Quick connect outlets simplify setup and reduce leaks.
- Durability: Heavy‑duty PVC and welded seams improve longevity in saltwater environments.
- Portability: Weight and foldability affect transport to the dock or on road trips.
Can a flushing bag double as a test tank?
Yes. Several models are designed to function as test tanks for diagnosing cooling issues or verifying proper water flow. This can save time during routine maintenance and troubleshooting.
What are common cautions?
- Check that hose connections are secure to prevent leaks during flushing.
- Some bags may exhibit light seam weeping during operation, which is typical for welded seams.
- Verify engine compatibility with bag dimensions before purchasing to ensure a proper fit.
How should I store a flushing bag when not in use?
Choose a bag with a roll‑up design or included storage bag to minimize space. Dry, cool storage helps prevent material fatigue and keeps the bag ready for next use.
