I'm sure we can get you a hub assembly for your Shorlander boat trailer, though we don't have any way of knowing off-hand or cross-referencing what bearings/hubs you need. So in order to find the correct hubs you will need to take apart your current hub assembly 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 a digital caliper measure your spindle to the thousandths of an inch where the bearings ride, like in the photo I added. You will also need to know your axle capacity (which should be stamped on the axle itself) and wheel bolt pattern. If you aren't sure what your wheel bolt pattern is I have linked a help article below which details how to find it.

For example, if you have a 2,000 lb axle with a 5 on 4-1/2" bolt pattern, and your bearings are L44649 (1.063" inner diameter) you would use the Trailer Idler Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 # AKIHUB-545-2-G-2K.

I have added a link below to our entire selection of hubs for you once you find this info, or if you get back to me with your bearing numbers or measurements I can try and find the right one for you.
