You need to make sure you remove all the identifying numbers and letters/name from the boat.
Completely illegal by Pa law and Coast Guard standards. Hull ID numbers can never be changed or altered and must remain with the boat till death. Removing all numbers, patching the boat or changing out a seat or rib does not make it a homemade boat. This happens to be what people who steal boats do and it’s why there are laws against it. I find it hard to believe a person responsible for registering and titling boats would recommend committing a crime over applying for a title.
§ 95.7. Hull identification numbers.
(a) A person who builds a boat for his own use shall identify the boat with two hull identification numbers that meet the requirements of this section.
(b) Persons who are required to identify boats under subsection (a) shall obtain the required hull identification number from the Commission. Application shall be made on forms provided by the Commission.
(c) Two identical hull identification numbers are required to be displayed on each boat hull. The first hull identification number shall be affixed as follows:
(1) On boats with transoms, to the starboard side of the transom within 2 inches of the top of the transom gunwale or hull/deck joint, whichever is lowest.
(2) On boats without transoms or on boats on which it would be impractical to use the transom, to the starboard outboard side of the hull, aft, within 1 foot of the stern and within 2 inches of the top of the hull side, gunwale or hull/deck joint, whichever is lowest.
(3) On catamarans and pontoon boats which have readily replaceable hulls, to the aft crossbeam within 1 foot of the starboard hull attachment.
(4) If the hull identification number would not be visible because of rails, fittings or other accessories, the number shall be affixed as near as possible to the location specified in paragraph (1).
(d) The duplicate hull identification number shall be affixed in an unexposed location on the interior of the boat or beneath a fitting or item of hardware.
(e) Each hull identification number shall be carved, burned, stamped, embossed, molded, bonded or otherwise permanently affixed to the boat so that alteration, removal or replacement would be obvious. A hull identification number may not be attached to parts of the boat that are removable.
(f) The character of each hull identification number may not be less than 1/4 of an inch high.
(g) A person may not remove or alter a number required by this section or 33 CFR 181.23 (relating to hull identification numbers required) unless authorized by the Executive Director.
