The Shamrock 25-9 Saddle (2-tank combo) OEM Replacement Fuel Tanks by Welding World are precision-engineered to restore the premium balanced performance, long-range cruising capability, and factory-spec reliability of your classic hull design. Masterfully fabricated from heavy-gauge, marine-grade 5052-H32 aluminum, this specialized 52-gallon port-and-starboard saddle combo system features a streamlined, low-profile contour tailored specifically to achieve a flawless, 100% drop-in fit within the narrow outboard hull cavities. To eliminate the severe risks of pitting, galvanic action, and crevice corrosion caused by trapped bilge water, the entire exterior surface of both fuel cells is fully encapsulated in a premium, anti-corrosive black TarGard epoxy coating. Inside the tanks, an engineered network of internal baffle plates suppresses fuel sloshing, ensuring exceptional lateral stability, optimized vessel trim, and continuous fuel flow during heavy offshore rollers. The flat top decks arrive pre-plumbed with heavy-duty mechanical hardware, featuring precision-welded fuel fill necks, integrated tank ventilation lines, electronic fuel level sending units, and high-flow brass 90-degree pickup elbows configured to match the original plumbing geometry perfectly. Built to satisfy or exceed all NMMA, ABYC, and USCG safety specifications, this rugged replacement saddle kit delivers a seamless installation and long-term structural integrity for demanding bluewater tracking.

 

  • Guaranteed to Fit Your Shamrock

Due to this item's size and weight we can only ship it in an economical way via Less Than Truckload (LTL) consolidated land shipping, and only to the contiguous 48 States.

For shipping inquiries to AK, HI, PR, US-VI, and international shipping, please contact us first at sales@weldingworldinc.com.

All of the destinations above we can only serve as a Free Carrier (or FCA) modality, that requires the customer to contract and pay for their carrier service of choice. We can still ship the item, but only to a warehouse/receiving office within the 48-contiguous States.

In plain terms what this means is that if you want to ship your product to any non-contiguous US territory or internationally, you, the customer, has to provide us with the warehouse address of the carrier that serves your locality with an address within the contiguous 48-US States, as we do not ship overseas on our own.
