T-H Marine Prop Master Prop Stop Propeller Stop

The T-H Marine Prop Master Prop Stop is a propeller safety tool designed for boaters who need a reliable way to secure their prop during maintenance and storage. Whether you're performing routine propeller service, changing out a damaged prop, or storing your boat for the season, this propeller stop locks your prop in place so it won't spin unexpectedly—eliminating the risk of injury and accidental damage to your vessel.

Propeller work is part of boat ownership, but it's also one of the more hazardous maintenance tasks. A free-spinning prop during hauling, repair, or storage can cause serious cuts or damage internal components. The Prop Master addresses this directly with a design that holds your propeller securely in position, giving you safe, hands-on access to do the work you need to do without distraction or worry.

Built from quality materials to withstand the marine environment, this prop stop is a practical addition to any boater's toolkit—whether you're maintaining an outboard, performing seasonal service, or simply parking your boat safely between trips. It's the kind of unglamorous but genuinely useful gear that prevents accidents and extends the life of your propeller and engine.
