Built to match common OEM thread sizes used on many older and modern 45HP+ outboards, the set helps technicians and DIY boat owners remove flywheels to access stators, triggers and other internal components, then lift or reposition the engine when needed.\u003c\/p\u003e\n\n\u003ch3\u003eWhich engines and years will this puller and lift ring work with?\u003c\/h3\u003e\n\u003cp\u003eThe Sporthfish set was made to fit a wide range of Mercury, Mariner, Force and Yamaha outboards, spanning historic models from the 1960s through recent designs. It targets 45HP and larger engines where the specified thread sizes are used on the crankshaft and bolt fittings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible brands: Mercury, Mariner, Force, Yamaha\u003c\/li\u003e\n  \u003cli\u003eCommonly used on 45HP and larger outboards\u003c\/li\u003e\n  \u003cli\u003eCovers many models from the 1960s to present\u003c\/li\u003e\n  \u003cli\u003eAlways verify thread dimensions before use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat thread sizes and fitment details should I check?\u003c\/h3\u003e\n\u003cp\u003eThread compatibility is critical for safe, damage-free removal. The puller uses a 1 1\/2\"-16 TPI threaded shaft to match crankshaft threads, while the lifting ring and bolt use a 5\/8\"-18 TPI thread that pairs with the puller assembly. Confirm these dimensions on your engine before proceeding.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePuller: 1 1\/2\"-16 TPI — matches crankshaft thread\u003c\/li\u003e\n  \u003cli\u003eLifting ring\/bolt: 5\/8\"-18 TPI — mates with the puller bolt\u003c\/li\u003e\n  \u003cli\u003eOEM-style threading for direct screw-in fit\u003c\/li\u003e\n  \u003cli\u003eMeasure your crankshaft thread if unsure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use the puller and lift ring safely?\u003c\/h3\u003e\n\u003cp\u003eStart by lubricating threads to prevent galling, then thread the puller into the crankshaft until it seats against the flywheel.

The Sporthfish flywheel puller and lift ring set is aimed at marine mechanics, boat owners who perform their own maintenance, and restoration shops working on older outboards. If you regularly remove flywheels to replace stators, do timing work or need a secure lifting point for 45HP+ Mercury, Mariner, Force or Yamaha engines, this set gives the correct thread sizes and protection to do the job properly. Always confirm your engine's thread specifications before purchase and follow safe lifting and torque practices when using the tools.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this puller fit my outboard crankshaft?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Check that your crankshaft uses 1 1\/2\"-16 TPI threads; the set matches that size and the lift bolt uses 5\/8\"-18 TPI.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the lifting ring to remove the motor from the boat?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the lift ring provides a safe lifting eye for hoisting 45HP+ outboards when correctly secured and used with proper lifting gear.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Sporthfish","offers":[{"title":"Default Title","offer_id":55162821902679,"sku":"B0D93WTFJ3","price":31.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/sporthfish-front-view-toolset.jpg?v=1790338980","url":"https:\/\/britishgarage.co.uk\/products\/sporthfish-flywheel-puller-kit-for-mercury-mariner-force-yamaha-45hp-4-piece-set-1-1-2-in-5-8-in-threads","provider":"British Garage","version":"1.0","type":"link"}
