Bunker, herring, and more, the Mega Mushmouth makes matching large baits easy.

Designed by Dave Skok, the Mega Mushmouth makes achieving large-profile baitfish imitations nice and easy. Built with a flexible spine and SF Fiber body, this fly prevents fouling and allows you to match large forage-like bunker and herring without trouble. Tie this fly in any color combos that you can come up with and fish the Mega Mushmouth with confidence whether you're on a New England beach during the fall run or fishing a deep drop miles offshore.

Recipe

Hook: Gamakatsu SC15-2H 2X Strong Wide Gap Hooks
Thread: Danville .006 Monofilament Thread
Flexible Spine: Just Add H20 Steve Farrar SF Blend and Hedron Mirage Flashabou
Body: Just Add H20 Steve Farrar SF Blend
Adhesives: Liquid Fusion and Solarez UV Resin (Thick)
Eyes: Hareline 3D Adhesive Holographic Eyes (Size: 3/8"; Color: Pearl)

Step One

Start the pattern by establishing a thread base from the hook’s eye to the point.

Step Two

One of Mega Mushmouth’s key characteristics is a flexible spine, and SF Fiber helps achieve this. Secure 10 inches of material at the shank’s center, with six inches extending beyond the hook’s bend. Be sure to clip the excess forward-facing material before moving on.

Step Three

Add bulk to the flexible spine by securing 30 strands of Flashabou material over the SF Fiber, extending just past the tail.

Step Four

Coat the first 30-percent of the spine with Liquid Fusion. This helps prevent foul hooking, especially when fish are blitzing.

Step Five

Tie on a large clump of olive SF Fiber on top of the shank, between the spine and eye. It is important to leave the outward-facing material intact.

Step Six

Secure an additional clump of white SF Fiber parallel to the olive on the shank’s bottom.

Step Seven

Apply another coating of Liquid Fusion to the front of both sections of SF Fiber material.

Step Eight

Fold the SF Fibers rearward, then rotate the fabric 360-degrees around the shank. Before moving on to the next step, secure the materials by tying down the front portion.

Step Nine

Secure two whip finishes, then apply the Solarez to build up the Mega Mushmouth’s head. Smooth the resin with the bodkin, then cure it with the light before tying the eyes.

Step Ten

Apply an additional coat of resin, place the eyes on the head, then cure it with the light.

Step Eleven

Finish the head by applying more adhesive between and around the eyes, then smooth over with the bodkin.

Step Twelve

The Mega Mushmouth is ready to hit the water after curing the resin.
