How many years do you think they are good for?

How they were installed dictates the lifespan of an aluminum tank. Too many variables to consider to give a definitive answer

Keep it dry on the outside and they are good for a very long time. Get them wet and stay damp then all bets are off.

My boat is a 2004. I have two 150 gallon aluminum tanks. They are both perfect, probably due to the design of where they live.

IF Grounded and no water inside - life of the boat.

It’s all about quality. The materials used and the install. Mine is circa 1988 and doing well.

Too many variables, location, environment of the location, gauge of aluminum, baffles, size of tank, how the boat is ran and treated, quality of welds ect. Tanks can fail for any number of reasons.

Would it stand to reason that a dry stored boat ( trailer/covered storage ) will last long than a wet slipped boat in the open? ie is it rain water that's killing them?

replaced my 1983 tanks in 2015, just because. After 32 years, they had given enough service to deserve retirement.

I hear ya...my boat is a 1996 Parker and it shows no signs of problems....my friend who has a 2012 Sea Pro had his tank rupture leaving gas in the bilge....frankly that scares the crap out of me...just wondering if I should go proactive on my tank....
