Would like to know what size to order, so I can replace when remove the old ones at one time. Your recommendation on a quality kit will be appreciated. Thank you.

The best way to identify correct replacement bearings for your 19-foot single-axle Continental Tilt C715 Boat Trailer is to locate the part number on the original bearings. An alternative method is to take measurements of the spindles but this method requires a precision digital caliper. Using the original part numbers is a much more reliable method.
Trailer manufacturers may sometimes alter the components used in their trailers from one production run to another. Since I do not know the model year of your trailer my contact at Continental could not provide an assurance of the particular bearings used in your trailer.
If you will refer to the linked photograph you will see examples of bearing (and seals) and where the part numbers typically appear. The photo also shows a spindle and where on the spindle measurements need to be taken for grease seals, inner bearings and outer bearings.
Once you know either the part numbers or the measurements you can use the link provided to visit our product page for bearings and choose replacements based on either the bearing number or dimensions. Filters at the left-hand side of the page will allow you to narrow the results to just those compatible with your trailer spindles.
I have also included a link to a helpful article concerning the process of replacing bearings.
