💡 What makes a positive displacement hand pump handy for transaxle maintenance?
1. Thick synthetic gear oils fail to flow freely without steady mechanical pressure.
2. Gravity siphons leave old sludge trapped inside sealed lower unit cavities.
3. Swivel couplers angle around fiberglass hull brackets to stop hose twisting.
4. Interchangeable barbs lock onto plastic fill necks without cracking threads.
