Get on plane with a heavy load.
Built for big boats and heavy hunting loads. The Hammer gets you on plane quickly, even in thick mud or dense vegetation, and pushes a heavy load with ease.
Is the Hammer right for your boat?
The Hammer is for higher horsepower motors, and for guys who care more about getting up on plane, shallow water and mud performance than they care about speed.
Big boats & heavy loads
Very good at pushing a load, and gets you on plane quickly even in thick mud or dense vegetation.
40+ hp
You need at least 40 hp to spin it efficiently. It's designed for 35–80 hp surface drive motors with a 3/4" hex driveshaft.
4,400 RPM
Your engine should reach at least 4,400 RPM with your stock prop in an empty boat. If it can't, adjust your gearing, add power, or choose a less aggressive prop.

Questions
Will the Hammer work on my motor?
It's designed for 35–80 hp surface drive mud motors with a 3/4" hex driveshaft, and you need at least 40 hp to spin it efficiently. Your engine should reach at least 4,400 RPM with your stock prop in an empty boat.
I run a GTR XD. Machined or adaptor?
Both fit. Machined means the prop fits your XD shaft directly with no adaptor. The adaptor option is a standard hex prop plus our XD Prop Adaptor, which lets you run any 3/4" hex Mud Buddy or non-XD Gator Tail prop on your XD.
