{"product_id":"21924267-propeller-kit-genuine-volvo-penta","title":"21924267 Propeller Kit | Genuine Volvo Penta Part","description":"\u003ch2\u003e\n 🔧 Product Description\n\u003c\/h2\u003e\n\u003cp\u003e\n Type J is a completely modern aluminium Duoprop range designed for the classic Volvo Penta 280, 290 and DP Aquamatic sterndrives. The patented blade geometry and large propeller diameter provide optimal efficiency as well as quiet and smooth operation, and a special high-strength aluminium alloy with a squeeze casting process makes the propellers stronger and more durable than traditional die-cast propellers. Four layers of paint ensure excellent corrosion protection performance. This number supplies the complete J7 pair, front propeller 21924227 and rear propeller 21924247. Every set of Duoprop propellers is designed, tested and manufactured together, so the front and rear propellers of a dimension belong to each other.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  AD, D, TMD, DP, HS, TAMD, KAD, KAMD\n \u003c\/li\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Year Range:\n  \u003c\/strong\u003e\n  Approximately 1980s onward as a modern replacement option for classic DP drives\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\n Full model list at the end of this description.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Type J7 Duoprop kit, front and rear on one number\n \u003c\/li\u003e\n \u003cli\u003e\n  For the classic 280, 290 and DP drives\n \u003c\/li\u003e\n \u003cli\u003e\n  Squeeze-cast high-strength aluminium alloy with four layers of paint\n \u003c\/li\u003e\n \u003cli\u003e\n  Three-blade front and four-blade rear propeller\n \u003c\/li\u003e\n \u003cli\u003e\n  7.257 kg for the kit\n \u003c\/li\u003e\n \u003cli\u003e\n  Also listed as front 21924227 and rear 21924247\n \u003c\/li\u003e\n \u003cli\u003e\n  Listed for 38 applications across the AD, D, TMD, TAMD, KAD, KAMD, DP, HS and 290DP series\n \u003c\/li\u003e\n \u003cli\u003e\n  M16 thread\n \u003c\/li\u003e\n \u003cli\u003e\n  Patented blade geometry and large active propeller diameter.\n \u003c\/li\u003e\n \u003cli\u003e\n  Strong and durable high strength aluminium alloy.\n \u003c\/li\u003e\n \u003cli\u003e\n  Excellent anti-corrosion performance.\n \u003c\/li\u003e\n \u003cli\u003e\n  Three-blade front propeller and four-blade rear propeller.\n \u003c\/li\u003e\n \u003cli\u003e\n  Replaces the Type A and Type B propellers.\n \u003c\/li\u003e\n \u003cli\u003e\n  Material: aluminium\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits: 280, 290, DP\n \u003c\/li\u003e\n \u003cli\u003e\n  Type: J7\n \u003c\/li\u003e\n \u003cli\u003e\n  Set contains: front 21924227, rear 21924247\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📋 Kit Contents\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Front three-blade Type J7 propeller - part number 21924227 - quantity 1\n \u003c\/li\u003e\n \u003cli\u003e\n  Rear four-blade Type J7 propeller - part number 21924247 - quantity 1\n \u003c\/li\u003e\n \u003cli\u003e\n  Propeller cone, nuts, washers, anodes and installation hardware are separate unless expressly included\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Supplies both counter-rotating propellers of a Duoprop drive as one matched pair, so front and rear stay at the same dimension and the torque split between them remains the one the drive was designed around.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Vibration through the hull that worsens with speed\n \u003c\/li\u003e\n \u003cli\u003e\n  Blade edges chipped, bent or eroded on either propeller\n \u003c\/li\u003e\n \u003cli\u003e\n  Loss of top speed, or slow to plane, at the same engine rpm\n \u003c\/li\u003e\n \u003cli\u003e\n  Engine over-revving under load, pointing to a slipped hub\n \u003c\/li\u003e\n \u003cli\u003e\n  Pitting or corrosion across the blade faces\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🛠️ Service Notes\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Order by the J number: the published kit weight is not the sum of its two propellers (7.257 kg for the kit against 5.148 kg and 5.058 kg for front 21924227 and rear 21924247), and four of the kits here are published at the same 7.257 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta's instruction for these drives is to fit stainless Type C propellers instead on six-cylinder diesel engines, on engines over 240 hp, and on boats capable of more than 38 knots (45 mph)\n \u003c\/li\u003e\n \u003cli\u003e\n  Do not mix Type A, Type B and Type J propellers on a drive, and use propellers of the same type and size on the drive - or on both drives in a twin installation; Type J is the modern aluminium replacement covering both Type A and Type B sizes, but the sizes do not transfer directly - an A5 is not a J5 - so size an upgrade with your dealer, giving maximum boat speed and engine rpm\n \u003c\/li\u003e\n \u003cli\u003e\n  Always use type C stainless steel propellers in 6-cylinder diesel engines or engines exceeding 240 hp or capable of speeds above 38 knots (45 mph).\n \u003c\/li\u003e\n \u003cli\u003e\n  Type J sizes are not equally transferred from Type A or Type B sizes - an A5 propeller does not correspond to a J5 propeller.
