Yamaha Water Pump Outter Plate EK-44323-00

<h2><strong>Genuine Yamaha Water Pump Outer Plate (6EK-44323-00) – Lower Unit Cooling Shield</strong></h2>

<p>Maintain the peak cooling performance of your outboard with the <strong>Genuine Yamaha 6EK-44323-00 Water Pump Outer Plate</strong>. This heavy-duty stainless steel plate serves as the critical base for your water pump assembly, providing the perfectly smooth surface required for the impeller to create maximum vacuum and pressure.</p>

<h3><strong>Product Overview and Technical Details</strong></h3>
<p>The Yamaha 6EK-44323-00 is a precision-stamped component made from high-grade, corrosion-resistant stainless steel. It sits directly beneath the impeller and above the lower unit housing. Because it is a genuine OEM part, it features the exact thickness required to maintain factory-spec water pressure and prevent overheating.</p>

<h3><strong>Precision OEM Compatibility</strong></h3>
<p>This plate is a direct fit for the following Yamaha models:</p>
<ul>
<li><strong>Yamaha F75 and F90 Series</strong> (Modern 4-Stroke Models)</li>
<li><strong>Yamaha F115 Series</strong> (Including F115B and LF115B)</li>
<li><strong>Yamaha F130 Series</strong> (4-Stroke VMAX and Offshore variations)</li>
</ul>

<h3><strong>Why This Component Is Essential</strong></h3>
<ul>
<li><strong>Perfect Sealing Surface:</strong> A mirror-finish ensures impeller blades move water efficiently without "bypass" leaks.</li>
<li><strong>Heat Dissipation:</strong> High-quality stainless steel manages friction heat generated by the spinning impeller.</li>
<li><strong>Corrosion Resistance:</strong> Specially treated to withstand saltwater environment, preventing the "bubbling" seen in cheap aftermarket parts.</li>
</ul>

<h3><strong>Symptoms of a Worn Plate</strong></h3>
<ol>
<li><strong>Deep Grooves:</strong> If you can feel "tracks" with your fingernail, it will shred your new impeller.</li>
<li><strong>Discoloration:</strong> Blue or "rainbow" tinting indicates the pump ran dry and overheated.</li>
<li><strong>Warping:</strong> A plate that isn't perfectly flat will allow water to leak out of the pump housing.</li>
</ol>

<h3><strong>Expert Installation Tip</strong></h3>
<p style="background-color: #f9f9f9; padding: 10px; border-left: 5px solid #ccc;"><strong>Pro Tip:</strong> Always replace the associated gaskets and the impeller key when installing a new outer plate. Applying a very light film of marine grease to the top of the plate helps the new impeller "seat" during the first few seconds of operation.</p>
