=== Assistant: Here’s a solid, field-proven foam fill approach specifically for marine use to mitigate your pod seam leak. ===
Here’s a solid, field-proven foam fill approach specifically for marine use to mitigate your pod seam leak. This setup balances expandability, sealing performance, and controllability.

===== Foam Kit Recommendation (Closed-Cell Marine Grade) =====

====== Option 1 – Most Control, Best Performance ======

TotalBoat 2-Part Polyurethane Flotation Foam (2 lb Density)
* Ideal for filling small voids with minimal risk of overexpansion
* Marine closed-cell, won’t absorb water
* Sold in quart, gallon, and 2-gallon kits

Link (TotalBoat site)
* For your use, 1 quart kit (~0.5 cubic ft expansion) may be enough, or get 1 gallon to have margin

===== Tools and Accessories You’ll Need =====

====== 1. Disposable Mixing Supplies ======
* HDPE mixing cups or paint buckets
* Stir sticks or paint paddles
* Nitrile gloves (this stuff is sticky and unforgiving)

====== 2. Injection Setup ======
* Large plastic syringes or squeeze bottles (e.g., condiment bottles or 100 mL epoxy syringes)
* Drill + 1/4" or 3/8" bit for injection ports along the seam
* Painter's tape to mark your holes and avoid mess

====== 3. Finishing Sealant ======

After the foam cures:
* 3M 4200 or 5200 Fast Cure over the seam line to add surface sealing
* Optional fiberglass tape + epoxy skim coat if you want to reinforce the outside

===== Application Tips =====
# Dry the Area Fully: Use a fan or compressed air if needed.
# Drill access holes every 4–6 inches along the pod-transom seam.
# Pre-tape below the holes to catch runoff.
# Mix and inject small batches (4 oz or less at a time) to avoid overfill.
# Let fully cure (~30 minutes for initial set, several hours for final hardness).
# Once cured, trim or sand any foam overflow.
# Seal surface with 5200, Sikaflex 291, or similar UV-stable marine caulk.

===== Optional Add-On =====

If you want a less permanent, removable solution:
* Use urethane rope caulk or butyl rubber tape to form a barrier outside the foam fill zone, so you can peel back and refoam later.

Would you like me to mock up a diagram showing foam injection locations and sealant passes on the pod seam?
