Beauty **and** brawn? That's a win-win!
Livorsi Marine’s outboard motor transom support plates are engineered to enhance the strength and durability of your boat’s transom. Designed to fit all leading outboard motor brands, these plates are available in both single-hole and two-hole configurations, offering reliable reinforcement for a variety of applications. Manufactured from premium materials, they come in your choice of polished stainless steel, clear anodized aluminum, or a clear anodized finish protected with a powder coat—ensuring long-lasting corrosion resistance and a clean, professional look.
These transom support plates are not just about aesthetics — they are designed to evenly distribute stress across the transom, helping prevent cracks and structural damage caused by engine torque and rough water conditions. Livorsi Marine offers customization options with available Livorsi or Contender logos, and OEM private labeling is available upon request with proper written approval. Most configurations are in stock and ready to ship the same day, making it easy to upgrade your transom reinforcement without delay.
Whether you’re a boat builder, service center, or performance enthusiast, Livorsi Marine’s transom support plates provide the strength, style and reliability your outboard-powered boat demands.
