Because propeller hardware can vary by drive family, propeller series, and front-versus-rear position, the safest fitment path is to match this nut to the exact Volvo Penta propeller hardware diagram and drive application before ordering.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eMatch Volvo Penta part number \u003cstrong\u003e3851335\u003c\/strong\u003e to your drive serial number and the correct Volvo Penta propeller hardware diagram before ordering. Front and rear Duoprop hardware can differ even within closely related setups, so exact application matters more than a visual size match.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eThis propeller nut should be replaced when threads are damaged, the nut shows corrosion or deformation, or when removal during propeller service reveals wear at the seating or locking surfaces. It is also smart to inspect it anytime the front propeller is already off, since worn prop hardware can create repeat labor or retention issues. This service guidance is an inference based on the part being identified as the \u003cstrong\u003efront propeller retaining nut\u003c\/strong\u003e in Duoprop hardware references.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eConfirm the exact application before installation, and compare the removed nut carefully against the replacement part, especially if the drive may have mixed or older propeller hardware.
