I own a 1998 and it has a wood transom. When Triton Came out with their complete Composite boats by the year 2000 all boat makers had gone complete composite to the best of my knowledge. I have a buddy that has a 2001 Skeeter ZX series and when he was installing a new transducer on the outside of his boat and was drilling holes he said there was no wood in his transom. I found this article in the Skeeter site that may help a little.
Composite One-Piece Floor: The floor of the SKEETER i-Class and ZX is one solid piece. It is composed of a PVC crosslinked foam, sandwiched between layers of fiberglass.
EX-Cel Composites, for the Industry's Strongest Hull: The transom, stringers and floor utilize aerospace derivatives known as EX-Cel composites, which provide outstanding strength and durability.
A Finish That Lasts: The polyflake finishes are applied using an exclusive "dry flake" system that allows the flake to be sprayed behind the clearcoat for a lustrous, durable finish that resists migration through the clear gel top coat and lasts longer. Additionally, it has our extra-tough Armorcoat? gel coats that are considered the best in the industry against weathering and blistering.
