Default Fuel Tank Condition

Hi All,

I am new to Maxums, in fact owning a boat in general. I'm an engineer on larger luxury motor yachts, hence my fairly large first leap into boat ownership. Nothing by halves hey. I am currently in the process of buying a 2005 Maxum 2900 SE. I am getting a full pre-purchase survey undertaken and have been sent a few pictures by the current owner. The boat looks beautiful and extremely well maintained but I noticed what looks like some corrosion on the fuel tank (or what of it I can see from the engine bay).

I have (hopefully) attached a picture, I'm not sure if you'll be able to make out what I am talking about but the aluminium tank at the top of the picture looks to be a bit corroded. I can't make out whether some of what I see is some kind of tape/cladding or all corrosion.

As Owners, is corrosion of the tank an issue?

Many thanks,

Chris

Welcome aboard

Not the best picture for getting a good look at the tank but there does appear to be some corrosion. Most fuel tanks fail on the bottom where water gets trapped. You can perform a pressure test on the tank to see if itís leaking but I would go in thinking the tank may need to be replaced in a few years. This is a big job and the engines need to come out to do so.

Hi Mike,

Thanks for your input, and yes, I was thinking the same. The thought of replacing the tank doesn't overly concern me as I have had to do the same with one of the Tenders to the vessel on which I work. Although it's very different when its somebody else's money you're spending.

On these Maxums, is there a need to cut out the cockpit floor as well? I know it's hard to say, but what do you think a rough estimate of cost would be? As the rest of the boat is in good condition I will need to decide whether it's still worth going for, or how much of a reduction to negotiate.

I've informed the surveyor and asked him to check thoroughly so we will see what he says.

Once again, thanks for the input.

The tank should only extend under the mid-cabin berth. It won't go past the bulkhead into the bilge space under the sole of the cabin.

Hi Chris, as shrew stated the fuel tank doesn't go past the bulkhead of the mid-berth. Typically the engines come out, the bulkhead behind the tank shown in the picture is cut away and the deck under the mid-berth is removed to access the tanks hold downs. The biggest cost is the tank and it you are paying someone to do the work I would double to triple that cost to cover the rest of the work.

Hi Mike/Shrew,

Thanks for the info. I'll see what the surveyor comes back with. As I say, it doesn't put me off completely but will depend on whether or not the current Owner will accept a significant reduction should the work be necessary in the near future. We will see and I shall keep you informed.

Many thanks,
