At any time that a mortgagee repossesses a vessel or motor on which the registration has become delinquent as of the date of such repossession, the mortgagee shall not be required, as a condition for registration of said vessel or motor to pay any of the penalties which had accrued as of the date of such repossession otherwise prescribed in the Oklahoma Vessel and Motor Registration Act. Provided that said penalties shall not be waived unless such vessel or motor is registered by the mortgagee within five (5) days after it is repossessed. Provided further, that if the mortgagor or spouse, becomes the owner of the vessel or motor within ninety (90) days from the date of repossession, the penalty shall reattach and be paid when application is made for the new title.
