Pontoon boats for Arizona lakes: what to look for when buying used
Pontoons are everywhere on Arizona lakes. They're stable, they fit a crowd, and they don't need much skill to run. But buying used means checking things most sellers won't bring up.
Check the tubes for soft spots
The tubes are the whole boat. Walk the length of each tube and press down every few feet. You're looking for soft spots, dents that don't pop back, or any area that feels different from the rest.
Aluminum pontoons can develop small leaks at the seams or from hitting rocks. Fresh water won't sink a pontoon quickly, but a slow leak means one tube is carrying more weight than the other. That makes the boat list to one side.
If the boat sits unevenly in the water when it's not loaded, one tube probably has water in it. Ask the seller directly. Some will admit it. Others will say "it always sits like that" which is not true.
Inspect the deck for rot and soft spots
Most pontoon decks are plywood covered with vinyl or marine carpet. Press down on the deck near the edges, around the furniture mounts, and anywhere you see staining or discoloration.
Soft spots mean the plywood is rotting. This happens when water gets under the carpet through tears, worn seams, or poorly sealed furniture mounts. Arizona heat makes it worse because it dries the top layer but traps moisture underneath.
Deck replacement is expensive. It's not a weekend project. If the deck has multiple soft spots, budget several thousand dollars for repair or walk away.
Test the furniture and railings
Sit in every seat and lean on every railing. Pontoon furniture is bolted through the deck into the frame below. If the deck is rotting, the bolts lose their hold and the furniture wobbles.
Check for rust on the frame under the seats. Arizona is dry, but water pools under furniture and in storage compartments. Rust on the frame means water has been sitting there.
Railing welds can crack from stress or impact. Run your hand along the base of each railing post and look for cracks or gaps. A broken weld isn't dangerous until it is.
Run the engine hard, not just idle
Ask to test the boat on the water, not just in the driveway with a hose. On the water, run the engine at full throttle for at least five minutes. Watch the temperature gauge.
Outboards on pontoons work harder than outboards on lighter hulls. If the engine overheats, the cooling system has a problem. That could be a clogged water intake, a failing impeller, or a cracked head. All are expensive.
Listen for rattles, knocking, or any sound that changes under load. Pontoon engines idle fine and fall apart at speed. The seller knows this. You need to hear it run hard.
Check for sun damage on upholstery and Bimini tops
Arizona sun destroys vinyl. Check the seats for cracks, fading, and hard spots. If the vinyl is brittle, it will tear soon.
Bimini tops fade and the stitching rots. Pull on the seams to see if they're still holding. A replacement Bimini costs $500 to $1,500 depending on size.
Carpet and vinyl flooring also fade and crack. If the carpet is worn through to the deck in high traffic areas, you're looking at replacement.
Verify the trailer is rated for the weight
Pontoons are heavier than they look. A 24 foot pontoon with furniture, fuel, and gear can weigh 3,500 pounds or more. The trailer needs to be rated for at least that much, ideally more.
Check the VIN plate on the trailer tongue for the GVWR (Gross Vehicle Weight Rating). If it's close to the boat's loaded weight, the trailer is marginal. Marginal trailers bend, crack, and lose bearings.
Inspect the trailer frame for rust, especially near the bunks and crossmembers. Trailers that sit outside in Arizona dust and monsoon rain rust faster than you'd expect.
Ask about Lake Pleasant or Bartlett use
Boats used on Lake Pleasant see waves, wind, and long runs. Boats used on smaller lakes like Bartlett or Saguaro see less stress. If the seller used the boat on Pleasant, check the tubes and hull more carefully.
Pleasant is also full of rocks near the shore and in shallow coves. Pontoon tubes show rock damage as dents, scrapes, and sometimes punctures. Minor dents are fine. Deep gouges are not.
What to pay for a used pontoon in Arizona
Prices vary by age, condition, and engine size. A 10 to 15 year old pontoon with a 90hp outboard and no major issues typically sells for $15,000 to $25,000 in Arizona. Older boats with smaller engines run $8,000 to $15,000.
Pontoons with triple tubes or performance packages cost more. So do boats with newer upholstery, upgraded sound systems, or recent engine work.

Red flags to walk away from
- Seller won't let you run the boat on the water
- One tube sits noticeably lower than the other
- Multiple soft spots on the deck
- Engine overheats or makes bad noises under load
- Trailer has visible frame damage or rust through
- Seller "doesn't remember" where the boat was used or how often
Pontoons are good boats for Arizona lakes, but used ones hide problems better than most boats. Check the tubes, test the engine hard, and walk the deck before you buy.
