🔌 Function

Carries the engine's weight into the bearer on its side of the block and holds the alignment set at installation.

⚠️ Common Signs of Failure

• Bracket cracked, most often at a radius or where the arm meets the mounting face
• Bolt holes elongated or wallowed where the fastener has been working
• Engine sitting low or out of line on one side, or the shaft alignment drifting
• Fresh bright rust or fretting powder around the mounting faces
• Vibration or a thump through the hull that changes when the boat is loaded

🛠️ Service Notes

• Engine bracket 860343 is the other half of the pair and is marked P - the two are within 9 grams of each other, so go by the marking rather than by weight or eye
• Check the alignment after fitting; renewing one side alone will move the engine relative to the shaft
• Inspect the opposite bracket at the same time - both have seen the same loading
