Expert Reply:
To verify the correct trailer hub for your boat trailer I will need some additional information on your current hub/spindle. With your trailer being manufactured in 2008 there is a chance there is an axle tag on it that will allow me to identify exactly what size spindle. This tag is typically on the center of the axle on the rear side of the axle tag. If you can send me an image of this tag I can reach out to the axle manufacturer to verify the correct size parts.
If you do not have the tag I will need for you to disassemble the hub and either measure the different diameters of the spindle or pull the numbers off the bearings and grease seal. The image below will show you where to measure the spindle with a Digital Caliper # PTW80157 or find the part numbers.
