No, this tool was designed with flexible mono filament line that will not puncture the   rubber Tell Tale hose. 

Insert the Pisser Fixxer tool into the Tell Tale. Use the minimum amount needed to clear the clog. Gently probe, twist and move back and forth until the obstruction is clear and the engine is discharging water that helps to cool the engine.

Absolutely! This tool makes it easy to unclog your tell-tale without harming hoses or internal parts. Using this unique tool eliminates having costly mechanics on the scene.

To save time and expense related to unnecessary towing and service calls. Keep this tool onboard for potential emergency situations. Any captain can easily use our original tool to clear the tell-tale from sand mud — and other debris that can stop your outboard from circulating water. Potential overheat situations may not be the case. The tell-tale gives the boater a visual confirmation that the engine is pumping water. Remember, if the tell-tell is not pumping water you can have big problems that may result in engine overheating. If your getting an over heat alarm please consult a certified mechanic. The Pisser Fixxer does not fix an overheating engine but is a great prevention tool. 

Most outboard engines include Yamaha, Suzuki, Mercury, Evinrude, Johnson, Honda Force and Tohatsu. Basically, any engine that has a tell-tale visual confirmation.
