<h3>About Water Sports, LLC &amp; Stream Machine</h3><p>Water Sports, LLC has been a fixture in outdoor recreation since <strong>1991</strong>, when the company introduced the original Stream Machine water launcher — a simple, pump-action water blaster that became a summertime staple for kids and adults alike. More than three decades later, the brand continues to deliver innovative, durable, and genuinely fun products for pools, beaches, lakes, backyards, and beyond.</p><p>Operating under the <strong>Stream Machine</strong> banner, Water Sports, LLC has grown its lineup well beyond its iconic water launchers. Today the catalog spans water blasters in multiple sizes and power levels, sand toys, inflatable pool toys, balloon launchers, geyser toys, and a full range of portable backyard games — everything a family needs to make the most of warm-weather days. The company is headquartered in North Aurora, Illinois, and remains committed to producing products that are accessible, easy to use, and built to withstand seasons of outdoor play.</p><h3>Stream Machine Water Launchers</h3><p>The core of the Water Sports, LLC lineup is its legendary Stream Machine water blaster series. Models like the <strong>TL-500, TL-600, and TL-750</strong> are engineered with a straightforward hydrobolic pump-action mechanism — submerge the barrel, pull back the handle to load, and push forward to fire a powerful stream of water. The TL-750, one of the brand&apos;s most popular models, measures 22 inches in length and is capable of shooting a steady stream up to 70 feet, making it a go-to choice for competitive backyard water battles. All Stream Machine launchers are injection-molded from high-quality, fade-resistant polymers designed to hold up through years of heavy outdoor use.</p><h3>A Full Lineup for Outdoor Fun</h3><p>Beyond water guns, Water Sports, LLC produces a diverse range of products suited for every type of outdoor gathering. Their <strong>Instant Fun Sports</strong> line features portable backyard games designed for quick setup, including variations on ring toss, corn hole-style games like Bulzibucket, bocce ball sets, and flying discs. The brand has also partnered with Diggin Active to expand its offering of year-round, active play products for children and families.</p><p>For beach and pool days, the Water Sports catalog includes sand toys, reusable water balloons, balloon launchers, geyser toys, and inflatable accessories — making it a one-stop source for outdoor water recreation. Whether you&apos;re heading to the lake, setting up at the neighborhood pool, or just looking for ways to keep the family entertained in the backyard, Water Sports, LLC has a product designed for the occasion.</p><h3>Built for Every Age, Every Occasion</h3><p>One of the defining characteristics of the Stream Machine brand is its broad age appeal. Smaller models like the TL-500 are sized appropriately for younger children, while larger models like the QF-2000 — the biggest launcher in the lineup at nearly 30 inches — deliver the kind of range and power that older kids and adults demand. With no batteries required and a fast 2-to-3-second reload time, Stream Machine launchers keep the action going without interruption. Explore the full Water Sports, LLC catalog and find the right product for your next outdoor adventure.</p>

Product Details

The WSM Performance 003-507 is an inexpensive replacement for the stock pump housing designed for Yamaha personal watercraft. This aftermarket jet pump housing addresses common issues with original equipment, as OEM impeller housings are known to warp and dimple due to corrosion between dissimilar metals.

Key Features:

  • Includes wear ring, made to the same size as the OEM Yamaha part with an upgraded removable plastic wear ring
  • Wear ring internal diameter: 144mm / 5-5/8"
  • Aluminum housing with plastic wear ring, instead of the thin stainless steel liner that corrodes and bulges
  • Very low cost plastic wear-ring liner is easy to remove and replace
  • Uses replacement wear ring part number 003-521 (sold separately)

OEM Cross-Reference: Replaces Yamaha part numbers 6R7-51312-00-94, 6R7-51312-01-94, 6R7-51312-02-94, 6R7-51312-03-94, and 6R7-51312-03-00.

This housing provides a cost-effective solution with the added benefit of a replaceable wear ring system, eliminating the need to purchase an entire housing when the wear ring becomes damaged from rocks, debris, or worn bearings.

Great confirmation that this would fit my application.

Easy

Needed some specialty parts to finish up a project, check Summit and it was going to be mid-month before the parts would be in stock...Autoplicity had them in stock and at a MUCH better price. First time customer soon to be a lifelong repeat customer!

Loved it, had what I need when I needed it, at a fair price.

Received Monroe MA770 air shock, fit just wonderful and the installation was easy.
