CMC 20022 Upper Transom Washer Plate 12-7/8"

The CMC 20022 is a precision-engineered upper transom washer plate designed to protect boat transoms from damage caused by outboard motor mounting bolts. This essential marine hardware component provides critical reinforcement for high-performance engine installations.

Key Features:

• Constructed from heavy-duty 3/8" thick 6061-T6 alloy aluminum (not cast aluminum) for maximum strength and corrosion resistance
• Prevents mounting bolts from "biting" into and damaging transom material
• Evenly distributes stress loads across the transom surface, ideal for high-performance outboard engines
• Upper plate design with hole centers spaced at 12-7/8"
• Compatible with CMC hydraulic jack plates, manual jack plates, and power lift systems

This transom support plate is an essential upgrade for boat owners running larger outboards or those seeking to extend the life of their transom. The 6061-T6 marine-grade aluminum construction ensures long-lasting durability in harsh saltwater environments.
