📋 Kit Contents

🔌 Function

The plate provides the rigid, sealed mounting surface that aligns the interceptor blade and servo mechanism with the hull bottom.

⚠️ Common Signs of Failure

• Water leakage around the mounting plate
• Corrosion, cracking or distortion of the plate
• Interceptor blade binds because the plate is misaligned
• Mounting screws loosen or threads are damaged
• Incorrect plate length or fastener count is fitted

🛠️ Service Notes

• Check the kit contents against the parts you remove before you start, and use the fasteners supplied with the kit rather than substituting whatever is to hand
• Clean the mating faces and check them for burrs, distortion, old sealant and corrosion; a plate that will not sit flat pulls whatever it carries out of line
• Assemble loose first, check the alignment of the component it supports, then tighten evenly and diagonally to the figures in the workshop manual for your engine
• Where the plate carries a gasket, seal or shim, renew it and keep the original order and orientation
• Recheck the fasteners after the first running period — mounting hardware is the first thing to move once the assembly has been through heat and vibration
