First, I appreciate help with knowledge/experience. Otherwise STHU. What is the paperwork that is needed to do this properly? Trailered boat and I do have AA. California and Oregon seem to be slightly different. Here it's easy transferring title. Can't believe I said that, California, something easy. Revised after first comment: Trailer has title similar to California, DMV. Boat is registered/managed by Oregon State Marine Board - Boats. If you have purchase a trailered boat from Oregon, you will know what I'm asking.
