The Megabass Marine Gang Cookai 90S is a high-performance sinking minnow “engineered” to dominate coastal environments where smaller forage is the primary target. At Gerry’s Fishing, we consider this lure a “technical essential” for “early season fishing” or those specific moments “when predators are concentrating on small prey.” At 9cm and 11.5g, it is the “smallest in the Marine Gang Cookai range,” yet it punches far above its weight class.
Equipped with the “revolutionary LBO II” mass transfer system, this lure “far outpaces conventional minnows,” making it an “absolute reference” for “reaching unexplored areas” even when using “finesse” tackle.
LBO II (Linear Bearing Oscillator): This patented “frictionless” weight-transfer system is “pure muscle” for your cast.2 It allows the 90S to “achieve exceptional casting distances,” “launching like a bullet” into headwinds that usually stall small lures.
Instant Action Response: Thanks to the “silky-smooth ball bearings,” the internal weight resets “instantly” upon hitting the water. This ensures your “lure action begins from the first turn of the reel handle,” “essential” for “short-range” strike zones.
Attractive Shimmies on the Fall: As a “sinking minnow,” the Cookai 90S “often attracts predators during pauses.” It performs a “particularly attractive rolling action” as it sinks, mimicking a “natural” wounded baitfish and triggering “vicious” strikes on the drop.
Versatile Retrieval Range: This “technical tool” is “designed to handle a wide range of retrieval speeds,” from a “vibrant” high-speed burn to a slow, “natural” drift through tidal currents.

The Marine Gang Cookai 90S is a “precision tool” for “studying the water” when the fish are keyed into small “sprats” or fry. The Gerry’s team suggests:
The “Match the Hatch” Tactic: In “early season” conditions, use the 9cm profile to mimic “small prey.” Its “natural” silhouette is “top-tier” for “fooling wary predators” that ignore larger, more aggressive lures
The “Stop-and-Sink” Trigger: When fishing over “submerged structures” or “rocky ledges,” incorporate frequent pauses. The “rolling action as it sinks” is “formidable” for “luring in predators” that are watching from the shadows.
Taming the Coastal Breeze: Utilize the “LBO II” system to hit “distant positions” from the shore.9 This lure “maintains its balance” in flight, allowing for “outstanding performance” even in “rough conditions.”
Estuary Current Play: Cast across the current and use a “steady retrieve.” The 90S will maintain its “stable action” even in “turbid” or fast-moving water, “essential” for “prospecting” estuary mouths.
Gerry’s Verdict:
The Megabass Marine Gang Cookai 90S (9cm/11.5g) is a “high-value” addition to any salt or freshwater box. It solves the problem of “poor casting with small lures” while providing a “vibrant” sinking action that “cannot be ignored.” For “extreme performance” in a “compact” frame, the 90S is “unstoppable
