<h3>About Acme Automotive</h3><p>Acme Automotive has built a strong reputation in the marine industry as a trusted manufacturer of precision-engineered inboard boat propellers and propeller accessories. Designed and crafted to exacting standards, Acme's marine products are a go-to choice for competitive water-skiers, wakeboarders, and serious boaters who demand reliable, high-performance hardware every time they hit the water.</p><p>What sets Acme apart is a relentless commitment to quality manufacturing. <strong>All Acme propellers and accessories are designed and machined to the highest quality standards</strong>, with the brand proudly serving some of the most demanding boat builders in the industry. Whether you're running a tournament-grade inboard ski boat or a family cruiser, Acme's catalog covers a wide range of shaft sizes, blade counts, and performance profiles to match your specific application.</p><h3>Prop Pullers Built for Inboard Boats</h3><p>One of Acme's most recognized product lines is its lineup of <a href="/4688-acme-automotive-prop-pullers-200815">prop pullers</a>. Inboard boats use a tapered prop shaft — a design that locks the propeller securely during operation but can make removal surprisingly difficult without the right tool. Acme's C-clamp style <a href="/4688-acme-automotive-prop-pullers-202386">prop pullers</a> are constructed from drop-forged aluminum for durability and long-term reliability, available in multiple sizes to fit 1&quot;, 1-1/8&quot;, and 1-1/4&quot; shafts, and compatible with both 3- and 4-blade propellers. For any inboard boat owner who carries a spare prop, an Acme prop puller is considered essential gear.</p><h3>Prop Nuts, Thrust Washers & Hardware</h3><p>Keeping a propeller properly secured to the shaft requires more than just the prop itself. Acme's <a href="/4688-acme-automotive-prop-nuts-thrust-washers-202385">prop nuts and thrust washers</a> provide the critical hardware needed for safe, correctly torqued propeller installations. Acme prop nut kits typically include a nylon lock nut, cotter pin, and key — everything needed to button up a prop change correctly and confidently.</p><h3>Clutch Hub Holders</h3><p>For technicians performing propeller service or drivetrain work on inboard vessels, Acme's <a href="/4688-acme-automotive-clutch-hub-holder-20250">clutch hub holder</a> is a specialized tool that simplifies the job. Holding the clutch hub steady during removal and installation prevents damage to drivetrain components and saves considerable time in the shop or on the water.</p><h3>A Brand Trusted on the Water</h3><p>From tournament ski boats and wake boats to cruisers and fishing vessels, Acme Automotive's marine lineup covers the full spectrum of inboard boating needs. With products found on MasterCraft, Malibu, Centurion, Supra, Tige, Nautique, and many other leading boat brands, Acme has become a staple name among boaters who take performance and reliability seriously.</p>
