T-H Marine G-Force Grass Goat Trolling Motor Weed Guard — Product description

Fishing in vegetation? Weeds wrapping the trolling motor prop kill your power and ruin your day. The Grass Goat deflects vegetation away from the prop so the motor keeps spinning clean.

The T-H Marine G-Force Grass Goat (MPN GFGG-MKL-DP) is a trolling motor weed guard that snaps onto the lower unit of a compatible bow-mount trolling motor and deflects vegetation away from the prop. If you fish anywhere with hydrilla, eelgrass, milfoil, lily pads, or any other heavy weed mat, the Grass Goat is the small accessory that lets you actually fish the cover instead of stopping every two minutes to clear the prop.

What it does. Soft-bodied trolling motors plow through weeds and the weeds get sucked into the prop, where they wrap around the shaft, around the prop blades, and against the lower unit housing. The motor slows down, draws more amperage (eating battery), and eventually stalls. The Grass Goat is a curved deflector that mounts on the leading edge of the lower unit, pushing vegetation aside before it reaches the prop. The deflection isn't perfect, but field reports consistently say it cuts prop-wrap incidents by 80 to 90 percent.

Why this matters. Bass tournament anglers and serious recreational fishermen know that the best summer cover is grass. Hydrilla mats, eelgrass beds, milfoil, even pad fields - these hold fish and they hold them densely. But running a trolling motor through that cover without a weed guard is a constant fight. You move into a pocket, the prop wraps, you back up to clear it, you ease in, the prop wraps again. With the Grass Goat installed, you can run the trolling motor through cover the way you used to wish you could.

The matched-brand compatible bracket. This variant is dimensioned for compatible bow-mount trolling motor lower units. The Grass Goat snaps onto the leading edge with a bracket sized to that lower unit profile. The fit is secure - it won't slip off during normal use - but you can pop it off in a couple of seconds for service or storage.

Install. The Grass Goat installs in under five minutes with no tools. Snap the bracket onto the leading edge of the lower unit, position the deflector blade, and you're done. To remove (for travel or service), pop the bracket off. No drilling, no hardware, no permanent modification to the trolling motor. Try it on one fishing trip and decide whether to leave it installed permanently.

Construction. The Grass Goat is molded from impact-resistant marine-grade plastic. The deflector blade has a curved leading edge that pushes weeds outward as the trolling motor moves forward. The blade is sized to deflect the typical weed mass without dragging the motor down. Marine-grade UV-stable material resists sun degradation and saltwater exposure, so the same Grass Goat lasts for multiple seasons of regular use.

Why pay for this. Three reasons. First, the time you save not clearing weeds adds up to extra fishing time per outing. Second, the battery savings from not bogging down through grass extends your trolling motor runtime on a single charge. Third, less stress on the trolling motor (lower amp draws, fewer overheating events from prop wrap) means longer motor service life. The investment is small and the return is direct.

One more practical note on usage. The Grass Goat is at its most effective when you slow the trolling motor down through heaviest cover (run it at lower thrust setting), which lets the deflector blade work the vegetation aside before it gets ingested. At full thrust in dense weed mats you might still get occasional wraps, but the rate is dramatically lower than with no guard. Most experienced anglers learn to vary their thrust setting to match the cover density: light cover at normal thrust, heavy mats at half thrust with the Grass Goat doing the deflection work. The technique becomes natural after a few outings and the combination of slower thrust plus the guard cuts prop wraps to nearly zero in cover that previously was unfishable.

Frequently asked questions

What does the Grass Goat do?

It's a weed guard that snaps onto the leading edge of your trolling motor lower unit. As the motor moves forward, the deflector blade pushes vegetation (grass, weeds, pads) outward so it doesn't get sucked into the prop. Net effect: 80-90 percent fewer prop-wrap incidents in heavy cover.

Will it fit my trolling motor?

This MKL variant is dimensioned for compatible bow-mount trolling motor lower units. The bracket profile matches the typical lower unit shape on the compatible product family. For unusual or oversized lower units, check T-H Marine's fitment guide before ordering. T-H Marine makes separate variants for other trolling motor brands.

Does it slow down the trolling motor?

Minimally. The deflector blade adds a small amount of drag in clean water, but the savings from not bogging through weeds (and the wear-and-tear from not prop-wrapping repeatedly) more than offset that small drag penalty. In clean water you might lose a small fraction of top speed. In cover, you gain dramatically more speed because the prop stays clear.

How does it install?

Snap the bracket onto the leading edge of the trolling motor lower unit. No tools, no drilling, no hardware. Total install time is under five minutes.

Can I remove it for travel?

Yes. Pop the bracket off in a couple of seconds and the trolling motor is back to stock. Many anglers install the Grass Goat seasonally (on for summer weed fishing, off for winter or open-water trips).

Will it work in lily pads?

Yes. Pads are actually one of the easier cover types because the leaves and stems push aside cleanly. Heavy submerged vegetation (hydrilla, eelgrass) is the harder case, and the Grass Goat helps significantly even there.

Does it work in saltwater?

Yes. Marine-grade UV-stable plastic resists saltwater exposure. Rinse with fresh water after saltwater days as standard maintenance.

Will it interfere with my transducer?

Not typically. The Grass Goat mounts on the leading edge of the lower unit, away from the transducer position (which is usually on the nose or bottom of the lower unit). For specific transducer setups, check the install position before ordering.

Does it scratch the trolling motor?

No. The bracket interfaces with the lower unit housing through molded contact points that grip without scratching. The plastic is softer than the housing finish so it won't mar the surface.

Will it stay on at speed?

Yes. The bracket grip is designed to hold under normal trolling motor speeds (up to full thrust). The Grass Goat is intended for trolling speed use, not for running the trolling motor at planing speeds, which you wouldn't do anyway.

What's the warranty?

T-H Marine standard warranty applies. Field reports indicate the product lasts multiple fishing seasons of regular use with no degradation.

Is one Grass Goat enough or do I need more than one?

One Grass Goat per trolling motor. The single unit handles vegetation deflection for the entire lower unit. No multi-unit setups needed.
