Do you think it's a good idea. I'll wash it everyday. Take note that those boats have rivets. Turner River Terror Posts: 8, Admiral. September 2. I've had Riveted and Welded. Running a Grizzly now and no problems. Have at it. No need to wash every day.. September 3. The only problem with aluminum boats especially the ones that come from a fresh water environment is that the owners have a tenancy to use non-stainless steel components.

Anything attached to the aluminum that is plain steel or galvanized steel will cause major corrosion. If the boat is done right you will have no issues, although I have seen problems with batteries causing bad corrosion on boats that were not wired properly too. I have a with a 20hp Sylvan that is about 25 years old and it has been used in salt water most all of it's life and there is zero corrosion on the hull. I did have to rebuild the transom due to corrosion, this time though, it was because of the pressure treated wood used in the transom by the manufacturer.

It is as good as new, even better now. So that is another thing to look out for, No Pressure Treated Lumber, unless you insulate it first like thoroughly coating it with epoxy, like I did with my transom wood. Tight Lines, Steve My posts are my opinion only. Be thankful we're not getting all the government we're paying for.

Will Rogers. September 4. I guess I have two problems with aluminum boats. One the cheaper boats often have rivets instead of welded. Second,riding around in a aluminum boat on a hot Fla. Flec Aluminum Boats And Saltwater Zip Code Posts: Officer. September 5. I have an aluminum Xpress bay boat and I have never thought of it as being hot to fish in. If the deck of your boat is a dark color it is going to get hot.

I had an Aquasport for a number of years with a grey deck and it would get warm to bare feet, and a GradyWhite with white deck that never got hot. My Xpress deck is white with black tufcoat speckles. But that is a minor issue, just start your fishing with the wind behind you. Belfast Bill Posts: 99 Deckhand. September 6. So, can you use an aluminum boat in saltwater?

Yes, you can use an aluminum boat in saltwater. He says that saltwater can corrode anything in your boat that comes in contact with it. However, Mr. All you need is a change in maintenance habits and anodes. Census statistics show that many veteran freshwater boaters eventually retire with their beloved boats to the warmer coastal climates. Fortunately, with a change in maintenance routine, they are able to keep everything in their boats one hundred.

Some of the maintenance changes you are going to have to make after transitioning from freshwater to saltwater include:. Also, change anodes yearly or when they get too wasted.

Worth mentioning is the knowledge that different propulsion systems get attacked in different parts, so watch out for that. But most importantly, know that not all salt waters are equal. Salinity varies from region to region and has been known to increase as warmth increases or from rainy to dry periods.

You have to be more vigilant when in higher-salinity waters as corrosion is much ferocious. In the presence of other metals, except Zinc and Magnesium, aluminum dissolves away. This is what is known as galvanic corrosion , do you remember your science classes? Just know that when aluminum is in electrical contact with other dissimilar metals, it experiences a galvanic reaction losing some of its items to the other metal. When it comes to boats, saltwater facilitates electrical contact.

So if your boat with an aluminum Thru-Hull is sitting in saltwater next to another boat with a different Thru-Hull, say bronze, expect your boat to get corroded.

For galvanic corrosion to occur, the metals in electrical contact must have different chemical activities. That is to say, one metal must be less active in the electrochemical schoolyard than the other.

In the electrochemical series, Magnesium is the most active metal followed by Zinc then our friend Aluminium, followed by Iron, Steel, Brass, etc. All you have to worry about is fouling. Use bottom paint to keep your boat clean.

But if you want to play it safe, a protective painting that uses an electrical barrier to keep water from aluminum is good for boats in both types of water. When painting your boat, however, the aluminum potion above the waterline can be left bare. This is because, with continuous exposure to oxygen, the aluminum part will develop a protective aluminum oxide layer that stops further corrosion.

Worth mentioning is that the electro-conductivity of saltwater increases with rising water temperature. So, boats in warmer coasts like Florida experience more galvanic corrosion than boats in the Chesapeake Bay. The galvanic reaction between an aluminum lower unit and a stainless-steel propeller in a boat shows the corrosive effects of saltwater. The aluminum is more chemically active than steel, so it is the anode, and steel is the cathode.

Electrons flow from the more chemically active aluminum lower unit via the saltwater to the stainless-steel propeller. The aluminum metal atoms that lose electrons become ions and are free to bind with the oxygen in the water to form aluminum oxide. Some of the aluminum oxide molecules drift away while the other settles onto the aluminum surface.

The bottom line, though, much thought goes into building an aluminum boat for those coastal waters. Most builders give it all they can use the right accessories, proper welding, and assembly.

Watch out for those aluminum anodes and replace them yearly or when they get more than half corroded.
