FYI for anybody in a similar situation:
The Texas Parks & Wildlife Department inspect these older inboards where there is no partial vin and the boat manufacturers label is missing from the engine. The inspection is conducted by a game warden (also a LEO) who assigns a new number to the engine. The form is a pwd130U, and can be completed for titling, registration or just for the boat buyer to pay sales tax. If the boat mfgs label is not missing, there is no point in assigning a number. The point of the inspection is to ensure the major assemblies are not in the system as being stolen.http://www.tpwd.state.tx.us/
The Texas Department of Motor Vehicles has the forms except for the one completed by the Public Safety, but they also provide information on the process. I spoke to them and they were very helpful:http://www.txdmv.gov/whatyouneed/forms/ ... ration.htm
I was told the vtr68a is a controlled form but I found it here:http://www.cctexas.com/files/g23/VTR-68-A.pdfhttp://www.cctexas.com/?fuseaction=main.view&page=2298
The Texas Department of Public Safety actually performs the 68a inspection. http://www.txdps.state.tx.us/vi/index.htm
The detective is performing basically the same inspection as the game warden, so they should recognize each other's authority. A form 130U from the warden for the boat and motor theft search along with the title should be all you need to satisfy the question of "Is it stolen?".
