Transom Plate Kit TSP1 and TSP2DP, Cast Aluminum, 2 Pack

Enhance your boat’s transom with the Transom Plate Kit TSP1 & TSP2DP, a durable two-pack of cast aluminum plates designed to reinforce the transom and evenly distribute engine mounting stress. Available in two practical sizes, 12" x 2" (TSP-1) and 15" x 2" (TSP-2DP), each plate is 3/8" thick and features universal bolt patterns to fit most outboard engines. By spreading the load from the outboard bolts, these plates help prevent transom fatigue and improve mounting stability, keeping your boat performing reliably mile after mile.

Benefits & Tips

• Universal bolt patterns and 3/8" thick aluminum provide solid, long-lasting transom reinforcement and straightforward bolt-on installation to the top bolt holes of outboard engines.
• Distributes engine-bolt stress across a wider area, helping balance the load and reduce stress concentrations that can lead to transom damage, vibration, and performance issues.
• Two size options cover common mounting patterns: TSP-1 (12" x 2") for standard top bolt holes and TSP-2DP (15" x 2") for larger or newer setups without twist clamps.
• Practical uses: retrofit an aging transom to extend life, upgrade for heavier engines on mid- to high-horsepower boats, or prepare a fresh installation for balanced performance and peace of mind.
• Friendly reminder: mounting hardware is not included; ensure proper alignment and torque when you install, and consider professional installation if you’re unsure about bolt patterns or fit.
