Cracked aluminum can be adequately repaired without welding using an epoxy embedded with aluminum. The aluminum particles contained in the epoxy will adhere to the cracked part, creating a permanent bond that will hold up in most situations. To ensure proper adhesion, you need to prepare the surface of the cracked part, as contaminants will interfere with the bond made between the aluminum epoxy and aluminum part. The amount of prep work required will depend on the type of cracked part you are repairing.
Spray the degreased cracked aluminum part with the 50/50 mixture to remove the degreaser residue from the surface of the part. Repeat the process if there is a lot of residue on the aluminum part. more
Wipe the 50/50 mixture from the surface of the aluminum part and allow the part to air dry. Make sure that the area to be repaired is completely dry before proceeding to the next step. here
Wipe the degreaser and freed grease from the aluminum part. more
Apply the degreaser to the cracked aluminum part and allow the degreaser to remove the grease from the aluminum part.
It follows that the longer cracks are left, the more extensively and deeply they will spread; until eventually the integrity of the panel will become compromised.
A disposable spray can be the best way to evenly apply the mixture across the surface. Spraying gelcoat is a lot different to spraying paint, it can be hard work to use, quite messy, and will not provide a smooth looking finish in the first instance. [links]
Next to re-spray the filled and sanded area. To do this, mix gelcoat, gelcoat reducer and hardener together in the ratios indicated by the manufacturer’s instructions. [links]

Thanks for the advice, so you wouldn't bother putting anything on the inside of the boat to seal it? Some of the cracks are on the corners or inside dented areas so might be hard to get the patch to conform to the shape of the boat perfectly. [links]
Safety glasses should always be worn when working underneath a boat. You don't want any of these compounds in your eyes. Wearing latex gloves to knead and apply each product is also recommended. The Epoxy in particular takes a vigorous scrubbing to clean off bare hands.
Tip: Shop boat supplies such as: cleaning supplies, boat carpet, battery chargers and more at Bass Pro Shops.
Generally regarded as simply a nuisance, the hard facts are that a leaky boat left unfixed can quickly become a sinking ship. Although major damage should be left to the professionals, those minor in stature can easily be fixed with a bit of DIY.
Ascertaining where water seeps in can be a tough chore. Problematic areas are often not noticed with a visual inspection, meaning a water test is your best bet.
Once leaks are located and marked, pull the drain plug and raise the bow. To ensure best results, leave the boat in this position for two days in order to completely dry. more
A common problem affecting aluminum boats are leaks. Collisions with underwater obstructions, beaching boats, and years of pounding waves are the likely causes of loose or missing rivets, widening of seams, and hairline cracks and tears.
