So...You need to replace your fuel tank?....

Most people don't think about their fuel tanks - until they fail. The ethanol additive to gasoline damages fiberglass tanks. Even metal tanks can fail. Replacement tanks are widely available. The challenge is accessing the tank. Often, a boat is literally built around the tank. When the tank in this trawler failed, the builder confirmed that the most efficient access to the tank was through the side. So here we go..... Fiberglass layer removed first. Now the core layer needs to be cut out completely, sawing through the entire hull structure.


Notice that we tape off the rest of the hull surrounding the repair site to protect it. Resin is used to fill the core area. Resin is applied to the area. Plastic is placed over the site and a double sticky tape is used around the edge to completely seal the area. A vacuum tube is placed into the edge of the sealed area. The vacuum forces the resin into every space in the repaired area.




Once this layer of resin has hardened off, another layer of resin is rolled onto the surface. Once this layer has set then the process of fiberglass application begins.... An un-structured fiberglass mat is applied and more resin rolled over. A woven fiberglass mat is then layered on top of this. Faring is then applied, sanded, applied, sanded... until all is completely smooth. Primer is applied and either Gelcoat or paint is applied to the hull, matched, buffed and worried over until there is no indication that the hull was ever touched


Here is a recent repair we did recently.... This SeaRay looks OK from the outside but has a leaking fuel tank and oh yea most of that side has delaminated too...with the new tank in place now for some major glass work. , .
