434676 – Transom Mounting Kit – OMC / Johnson / Evinrude

The 434676 transom mounting kit is a genuine OMC/Johnson/Evinrude OEM hardware kit used to secure an outboard motor to your boat’s transom. This kit includes mount bolts, large washers, and any mounting hardware needed to fix the motor bracket assembly firmly to the transom. It supports engines and keeps them properly aligned for safe operation on the water.

This transom mounting kit fits a range of OMC, Johnson, and Evinrude outboards, particularly models in the 35 HP, 40 HP, and 50 HP classes where part number 434676 appears in parts diagrams and inventory listings.

When you install the 434676 transom mounting kit, you give your engine a strong, reliable attachment point. Furthermore, proper mounting hardware helps prevent damage to both your boat and motor during vibration and dynamic loads while underway. You should inspect transom bolts and washers whenever you remove the motor or perform routine service. Doing so helps you catch rusted or worn parts before they fail.

Also, many boaters replace this kit when they refurbish older mounts or upgrade their hardware to correct fit and finish. Using correct OEM parts ensures proper torque and avoids mismatches that can cause leaks, wobble, or movement at speed. If you reuse old bolts or inferior hardware, you risk loosening and corrosion under marine conditions.

In addition, this kit includes oversized washers that spread load and protect your transom board. These washers help distribute pressure from the mounting bolts over a larger surface area so that wood or fiberglass doesn’t compress excessively.
