The Geecrack Imo Kemushi 40F (Floating) is the ultra-finesse, downsized topwater insect bait within this revolutionary Japanese soft plastic family. Meaning potato caterpillar in Japanese, the Imo Kemushi features a short, compact body completely bristling with fine silicone rubber hairs protruding from every angle.

While the larger versions are designed for heavier gear, the 40mm size is a dedicated micro-finesse masterclass. Poured from a specialized, ultra-buoyant elastomer material, this tiny bait sits perfectly proud in the surface film. It provides a flawless match-the-hatch profile for hot summer days when predators are selectively keyed into small terrestrial insects, beetles, and caterpillars that have lost their grip on overhanging branches.

Detailed Specifications

• Length: 40mm (Approx. 1.5 inches)

• Quantity: 4 lures per packet

• Type: Micro Topwater Finesse Insect Bait

• Material: Ultra-buoyant, high-stretch Elastomer compound infused with Geecracks original S.A.F. Formula (Salt + Amino Acid + Flavor).

• Action: Subtle surface wiggle, producing precise concentric micro-ripples from the radiating silicone legs.

• Recommended Hook Configuration: Size 4 to Size 2 Fine-Wire Finesse Offset Hooks, or an unweighted wide gap worm hook.

Key Features & Design Performance

• Micro-Insect Silhouette: The 40mm frame delivers a highly realistic, non-threatening footprint. To a predatory fish looking up toward the light, the radiating silicone hairs break up the hard outline of the body perfectly, turning it into a hyper-realistic silhouette of a struggling bug.

• Concentric Ripple Generation: When twitched softly on a slack line, the Imo Kemushi 40F doesnt glide or dive. Instead, it pulses on the spot, causing the fine legs to flare out and send distinct, tight rings of surface ripples outward to call fish in from deep cover.

• Pungent S.A.F. Taste & Scent Core: Infused with Geecracks signature blend of Salt, Amino Acids, and Flavor, it releases a potent olfactory trail. Because it tastes like a natural organism, hyper-wary fish will firmly inhale and chew the bait, giving light-game anglers plenty of time to set the hook.

• Tough-As-Nails Elastomer Construction: Made from a specialized floating elastomer, this tiny lure is practically indestructible. It stretches endlessly without tearing, easily shrugging off violent strikes from toothy predators and allowing you to skip it repeatedly against solid structures without the body sliding down the hook shank.

Where & How to Use It

• Overhanging Trees & Canal Margins: The ultimate summer approach. Pitch the 40F directly beneath overhanging bushes, weeping willows, and reed beds where caterpillars and terrestrial bugs naturally tumble into the water.

• LRF Harbor & Pier Finesse: A highly effective choice for light saltwater game. Work it along harbor walls, lock gates, and under pontoons to fool selective school bass and surface-feeding fish that are chasing micro-organisms in the surface film.

• Shallow River & Stream Pools: Exceptional for drifting down fast-flowing streams into calm pools for wild trout and chub, mimicking a drowned terrestrial beetle washing down-stream.

• Target Species: Specimen canal and river perch, chub, and trout in freshwater; school sea bass and various light-rock game species (LRF) in saltwater.

Pro Tip

The Micro-Shake Technique: Due to its tiny 1.5-inch profile and light weight, you must fish this bait with total finesse. Cast it tight against structure and let it sit entirely motionless for 10 seconds until all the entry ripples fade. If a fish doesnt smash it on the drop, simply shake your rod tip lightly against a semi-slack linedo not wind the reel handle. The goal is to make the line vibrate just enough to animate the silicone hairs on the spot. This subtle, localized twitching is the ultimate trigger for educated canal perch.

Frequently Asked Questions

Can I store the 40F model with my standard soft plastic worms?

No, absolutely not. The Imo Kemushi 40F is made from an advanced elastomer compound. If elastomer comes into contact with traditional PVC plastisol soft baits, a severe chemical reaction will occur, causing both lures to melt, deform, and turn into a sticky, ruined mess. Always store them in their original plastic clamshell tray or a dedicated elastomer-safe tackle box.

What type of line setup is best for this ultra-light floating bait?

To cast a 40mm weightless elastomer bait effectively, you need an ultra-light spinning or LRF setup. Use a very thin braided main line (PE 0.2 to PE 0.4) to maximize casting distance. Always tip it with a short monofilament leader (3lb to 5lb test) rather than fluorocarbon. Monofilament floats, whereas fluorocarbon sinks and will drag the nose of this micro-insect subsurface.

Does it float even when rigged with a wide gap hook?

Yes. The elastomer compound is incredibly buoyant and possesses more than enough lifting power to keep the bait floating flush in the surface film when paired with a standard fine-wire finesse or offset worm hook (Sizes 4 to 2). Avoid heavy-gauge or weighted hooks to preserve its delicate topwater presentation.
