S.C. Code Ann. § 50-23-450: Outboard motor registration applications.

(A) Every person who acquires an outboard motor required to be registered under this article shall register with the department within thirty days of the date of acquisition. The registration must be completed on forms required by the department. The fee for registration is ten dollars. The registration must be signed by the person who acquires the outboard motor and must contain:

(1) the applicant's name, domiciled address including the county, date of birth, and the county where the outboard motor is principally located, state-issued identification number, and state of issue;

(2) its make, model, and horsepower, and manufacturer's serial number, whether the outboard motor is new or used;

(3) the date of acquisition by the applicant, the name and address of the person from whom the outboard motor was acquired; and

(4) a bill of sale.

(B)(1) When a Transfer on Death (TOD) beneficiary is designated, the registration must contain each TOD beneficiary's name, domiciled address, including the county, date of birth, state-issued identification number, and state of issue.

(2) In the case of one or more TOD beneficiaries receiving the title and registration to an outboard motor, a bill of sale may not be required for the department to issue a title, but such TOD beneficiaries shall establish the death of all owners of outboard motors.

(3) The fee to establish, modify, or revoke a Transfer on Death designation upon a registration is ten dollars.

(C) Every dealer selling or exchanging an outboard motor subject to registration under this article shall complete the registration in the name of the purchaser at the time of delivery of the outboard motor to the purchaser. The registration must be signed by the dealer showing the assigned dealer permit number, as well as by the owner, and the dealer shall submit the application to the department within thirty days of the sale. However, permitted marine dealers are not required to obtain registrations for new or used outboard motors held in their inventory for sale until they are sold or exchanged as long as a proper manufacturer's or importer's statement of origin or title is held by the dealer. The fees for registration may not exceed those required by this article and if requested must be itemized on the bill of sale to the new owner. This does not prohibit a dealer from charging an administrative fee for registration.

(D) If a dealer buys or acquires an outboard motor for resale and the outboard motor is already covered by a registration, the dealer need not send the registration until the outboard motor is transferred.

(E) When an application for a watercraft title and certificate of number includes an application for an outboard motor registration number, and the application is filed thirty-one days or later after the acquisition date, only late fees for the watercraft title must be assessed.

(F) A registration, except those from permitted marine dealers, submitted after thirty days is subject to a late penalty of fifteen dollars.

(G) A registration submitted after sixty days is subject to a late penalty of thirty dollars.

(H) The provisions of this section requiring a fee do not apply to outboard motors owned by volunteer rescue squads used exclusively for the purpose of the squads.
