Some equipment needs to be specified on the boat bill of sale. Trailers and motors need their section if they are part of the transaction. Electronics, spare props, and recreational equipment, if part of the deal, do not need sections on the bill of sale. Some templates have subsections where the seller can list any additional equipment that is part of the transaction. This is where the seller can list out whatever small equipment is included. It is not technically required. A boat bill of sale drafted from scratch should include a section for additional equipment.
