If you like the boat, don't worry about the trailer. Just wash it down with soapy water when you're done with each trip. Springs, axles, some rims, brackets, bolts and nuts aren't galvanized. With proper care who knows how long it'll last. Don't be afraid of saltwater with your trailer. If you bury a galvanized trailer in saltwater at the ramp you may not damage the frame, but other components will take a beating without proper maintenance. Use and enjoy the boat, just clean the trailer after each trip. P.S. Used trailers for a V-20 are pretty reasonable on this site. For 8K I'd want compression numbers and hours on the motor, electronics, a solid transom, floor, bulkheads, and the tank cover pulled and inspected. I'd rather have a freshwater 1993 motor than a galvanized trailer anyday.
