We can help you determine the correct replacement hub assembly for your boat trailer. In order to find the correct replacement hubs for your trailer you need to know the weight rating of your axle, and also what bearings your current hub has.

You will need to take apart your current hub assembly - which it looks like you have already done - and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached to see exactly where you need to measure.

Additionally, you need to know your hub's wheel bolt pattern; if you do not know what it is I have added a help article which details how you can find it, as well as a printable bolt hole template you can use. If you get back to me with this information I'd be happy to try and help you find the correct hub. I have also added a link to our entire selection of hubs for you to come back to.
