The prop shaft transmits rotational power from the lower unit gearcase out to the propeller, and a worn, corroded, or bent shaft is a common cause of vibration, reduced thrust, or seal leakage at the propeller end of the drive. Machined to precise tolerances, the 18-2166 is built as a direct-fit alternative to the original equipment shaft, using the same mounting interface so no modification to the lower unit housing is needed during installation. This shaft carries Sierra part number 18-2166 and cross-references to multiple Mercury Marine and MerCruiser OEM numbers, so it can be matched to your old shaft or parts diagram regardless of which OEM number is stamped on it. Because a prop shaft carries continuous rotational load and sits at a water-exposed seal interface, replacing a worn or damaged shaft promptly helps prevent secondary wear to the gearcase bearings and seals.

used.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e

Each locknut is machined from stainless steel with a nylon insert, which resists loosening from vibration and keeps a secure, corrosion-resistant hold in a wet marine environment.

Keep a spare on hand whenever servicing your propeller, since prop nuts should be inspected for thread wear or damage each time the propeller is removed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-3726\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Prop Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e Prop Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 12mm (M12)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type:\u003c\/strong\u003e Unified National Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style:\u003c\/strong\u003e Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Coverage:\u003c\/strong\u003e Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Class:\u003c\/strong\u003e Class 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Head Style:\u003c\/strong\u003e Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Style:\u003c\/strong\u003e Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Groove Diameter:\u003c\/strong\u003e 12 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Rating:\u003c\/strong\u003e Industrial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e09141-18005\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3726 Prop Nut replace?\u003c\/strong\u003e The Sierra 18-3726 Prop Nut directly replaces OEM part number 09141-18005, so it installs as a drop-in equivalent using the same thread engagement as the original nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-3726 prop nut made from?\u003c\/strong\u003e It is machined from brass, a material chosen for its corrosion resistance in marine environments and its ability to hold up under the torque loads placed on a propeller nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does this prop nut use?\u003c\/strong\u003e The 18-3726 uses a 12mm (M12) Unified National Coarse thread, fully threaded, with a right-hand thread direction and a Class 3A thread fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-3726 weigh?\u003c\/strong\u003e This prop nut weighs 0.13 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-3726 prop nut?\u003c\/strong\u003e Item dimensions are 0.39 x 0.39 x 0.39 inches, consistent with a compact single hex prop nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-3726 meet OEM quality standards?\u003c\/strong\u003e Yes, Sierra manufactures the 18-3726 Prop Nut to meet or exceed the original equipment part it replaces, part number 09141-18005.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many prop nuts come in one purchase?\u003c\/strong\u003e One Sierra 18-3726 Prop Nut is included per purchase;

Instead of carrying a separate wrench for every prop nut size, this kit covers 9 of the most common prop nut sizes, from 17\/32 inch up to 1-1\/4 inch, in one compact tool. The wrench body is constructed from engineering composite resin, giving it a strong, lightweight build that resists corrosion in a marine environment. Because it is made from composite resin rather than metal, the wrench floats, so if it goes over the side during a prop swap it will not sink out of reach. The high visibility yellow finish makes the wrench easy to spot in a tackle box, on deck, or floating in the water. The kit uses a hex head style with a socket end for engaging prop nuts, and is sized to SAE (inch) measurement standards. It ships as a complete set including the wrench and 8 nuts, ready to store in a boat's tool kit or glove box for on-the-water prop

It features a 3-blade, cupped configuration for improved bite and holding power, and is cast from a high-grade aluminum alloy engineered for trouble-free service and easy repairability. Every Michigan Wheel propeller in this line uses a rubber hub bonded inside the propeller body, which acts as a shock absorber to help protect the boat's shaft, motor, and gear case from impact damage if the blades strike an underwater object. Because the finest grade alloys are used in construction, these aluminum props are built to be stronger than many original equipment propellers while remaining significantly more affordable to replace than a stainless steel unit. The Michigan Wheel 11028 is backed by a limited lifetime manufacturer's warranty, giving boat owners long-term confidence in the casting and hub bonding. This propeller is a straightforward, drop-in style replacement or spare for outboard applications matching its 11.75 x 17 cupped specification, and its rubber hub design means it also functions as a shear-pin-free impact buffer rather than relying on a separate sacrificial part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Michigan Wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 11028\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 11.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch:\u003c\/strong\u003e 17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Blades:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Design:\u003c\/strong\u003e Cupped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum with bonded rubber hub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Type:\u003c\/strong\u003e Rubber, bonded inside\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Michigan Match\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited Lifetime Manufacturer's Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Michigan Wheel 11028 propeller?\u003c\/strong\u003e The Michigan Wheel 11028 measures 11.75 inches in diameter with a 17 inch pitch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many blades does this propeller have?\u003c\/strong\u003e It is a 3-blade design, part of Michigan Wheel's Michigan Match series.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 11028 propeller made from?\u003c\/strong\u003e It is cast from a high-grade aluminum alloy with a rubber hub bonded inside the hub body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the propeller have a rubber hub?\u003c\/strong\u003e The bonded rubber hub in the Michigan Wheel 11028 acts as a cushion, helping protect the shaft, motor, and gear case from damage if the blades strike an object underwater.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 11028 a cupped propeller?\u003c\/strong\u003e Yes, the Michigan Wheel 11028 uses a cupped blade design for improved grip and holding power.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Michigan Wheel 11028 weigh?\u003c\/strong\u003e This propeller weighs 4.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this propeller stronger than the original equipment prop?\u003c\/strong\u003e Michigan Wheel builds the 11028 from finer grade alloys than many original equipment aluminum propellers, resulting in a stronger casting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Michigan Wheel 11028 come with a warranty?\u003c\/strong\u003e Yes, it is backed by a limited lifetime manufacturer's warranty from Michigan Wheel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Michigan Match series?\u003c\/strong\u003e Michigan Match is Michigan Wheel's line of aluminum replacement propellers, of which the 11028 (11.75 x 17, cupped, 3-blade) is a member.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 11028 an aluminum or stainless steel propeller?\u003c\/strong\u003e The Michigan Wheel 11028 is an aluminum propeller, not stainless steel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes in the box with the 11028 propeller?\u003c\/strong\u003e The Michigan Wheel 11028 ships as a complete 3-blade aluminum propeller with the rubber hub already bonded inside.\u003c\/p\u003e","brand":"Michigan Wheel","offers":[{"title":"Default Title","offer_id":48991272435931,"sku":"MIW-011028","price":232.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Michigan-Match-3-Blade__57392.1722380348.500.750.jpg?v=1785188931"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/collections\/41TvIgajcgL.jpg?v=1785356481","url":"https:\/\/www.goodvibesmarina.com\/collections\/gvcat-propellers-drive-lower-unit-propellers.oembed?page=11","provider":"Good Vibes Marina","version":"1.0","type":"link"}
