Thank you for the photo of your boat trailer's square axle.

Typically a square trailer axle that measures 41mm (1.6-inches) on a side will have a weight rating of 1800- or 2000-lbs. We offer one such 1800-lb-rated axle, CE Smith Trailer Axle # CE33201GA-HUB which includes idler hubs, and # CE33201GA which is the axle beam/spindles only.

We also offer Timbren axle-less trailer suspensions that entirely do away with the axle beam and leaf springs. These bolt-on kits like # A20RS440 are shown on the linked axle page. Timbren suspensions can give you much-improved ground clearance and they come with lift or drop spindles too for instances where you want to raise or lower the trailer height.
