Frequently asked questions
-
How much does a used tandem-axle boat trailer cost?
- Tandem-axle trailers commonly sell for 1,500 to 4,000 dollars used, with aluminum models and those with brakes on both axles costing more. The load rating, brake condition, and frame material drive the price.
-
When do I need a tandem-axle trailer?
- Tandem axles suit heavier boats, generally over about 3,000 pounds loaded, and add stability at highway speed plus a safety margin if one tire fails. Larger runabouts, cruisers, and offshore boats need them. Match the trailer's total rated capacity to your boat's fully loaded weight.
-
What should I inspect on a used tandem-axle trailer?
- Check all four wheels' bearings and all four tires, and confirm the brakes (surge or electric) actually engage, since brakes are common on tandems and required by law over a weight threshold. Inspect the frame for rust and cracks, and check the coupler, chains, and bunks. Brake and bearing service on a neglected tandem can add up, so factor it in.
