When purchasing a used aluminum boat, you should look for the following features:

The most dangerous and expensive problem to seek is a broken steering system when checking for old aluminum boats. Look for any signs of wear or tear, or leakage in the engine bay, when looking for tear and wear on the connectors and mounting points, as well as an outboard motor.

Bellows are key to the floating of an aluminum boat!
