Description:
110-200000 – Transom Backing Plates Set (Upper and Lower)
Protect and Strengthen Your Boat’s Transom
Machined from aircraft-grade aluminum plate for exceptional strength, lightweight design, and superior corrosion resistance in marine environments — outperforming weaker cast alternatives for reliable, long-lasting support.
This set includes both an upper and lower plate to reinforce your boat's transom by spreading outboard engine mounting bolt load and stress across a wider area, helping prevent cracking, flexing, or long-term damage. Essential for repowers, jack plate installations, high-horsepower setups, or rough-water use. Optional double top bolt configuration available for added reinforcement on the upper plate.
Compatible with all standard BIA boat mounting patterns on most outboard motors.
Key Features:
• Machined aircraft-grade aluminum plate – strong, lightweight, and built to last
• Distributes engine load across the transom beyond individual bolts/washers
• Excellent corrosion resistance (natural machined finish)
• Perfect complement to jack plate installations
• Clean, professional appearance
