T-H Marine Prop Master: The Original Molded Propeller Wrench
When it comes to outboard propeller maintenance, having the right tool makes all the difference between a quick dockside fix and a frustrating ordeal. T-H Marine — a family-owned marine accessories manufacturer with roots stretching back to 1975 — brought their signature problem-solving engineering to the propeller tool category with the iconic Prop Master™, widely recognized as the original molded propeller wrench.
The Prop Master™ is purpose-built for outboard owners, specifically designed to fit all 1-1/16" six-point prop nuts commonly found on higher-horsepower engines from OMC, Johnson, Evinrude (40 HP and up), and Mercury (50 HP and up). Rather than reaching for a bulky metal wrench that can rattle around your bilge and potentially scratch your hull, the Prop Master™ offers a dedicated solution engineered specifically for this single, critical task.
Why Nylon Outperforms Metal on the Water
T-H Marine's in-house plastic injection molding expertise — through its subsidiary, Innovative Plastics — gives the Prop Master™ a genuine manufacturing advantage. The wrench is molded from high-tensile strength nylon that resists stripping, won't corrode in saltwater environments, and stands up to exposure from fuel, UV, and harsh marine chemicals. Unlike metal alternatives, it won't mar finished surfaces or rattle loudly in a storage compartment.
- Six-point socket style provides a secure, slip-free grip on prop nuts
- High-visibility yellow color makes it easy to locate in dark boat compartments
- Durable nylon construction is fuel, sun, saltwater, and chemical resistant
- Includes a bonus 9/16" garboard drain plug socket on the reverse side
- Lightweight and compact — ideal for keeping aboard for on-the-water emergencies
A Complete Propeller Maintenance Solution
For boaters who want a full-service propeller maintenance kit, T-H Marine also offers the Prop Master Propeller Stop & Wrench Bundle, which pairs the wrench with a dedicated Propeller Stop. The Propeller Stop secures the prop against rotation during removal or installation, adding a critical layer of safety when working on your outboard. Whether you're swapping props between fishing spots or performing routine maintenance back at the dock, this two-piece system covers both jobs efficiently.
The thoughtful dual-function design — with the garboard drain socket molded right into the back of the wrench — reflects T-H Marine's broader design philosophy: practical, boat-specific tools that do more with less. It's the kind of detail that comes from a company whose team members are boaters and anglers themselves.
