Wilderness Systems Tsunami Bulkhead

No, this specific bulkhead is designed exclusively for the Tsunami 165. It will not fit other models in the Tsunami series or other Wilderness Systems kayaks due to differences in hull shape and dimensions.

Yes, you will need a high-quality marine-grade waterproof sealant to ensure a watertight bond between the foam and the hull. We recommend cleaning the interior surface thoroughly before application to ensure the sealant adheres properly.

Because this is a precision-cut replacement part for the Tsunami 165, it should fit without modification. However, if you find minor discrepancies, you can carefully trim the EVA foam with a sharp utility knife, though we advise measuring twice before cutting.

The two-inch EVA foam provides a balance of rigidity and flexibility. It is durable enough to maintain the structural integrity of the storage compartment while offering enough 'give' to absorb impact and vibration without cracking the hull.

You should replace your bulkhead if you notice water leaking into your cockpit from the storage hatch, or if the existing foam is crumbling, detached from the hull, or showing significant signs of dry rot.
