Built from heat-treated carbon steel and finished for corrosion resistance, the kit replaces part number 3855516 and is supplied as two separate tools sized for the front and rear prop. The design concentrates leverage at the right points so one person can handle prop changes on the dock or in the yard more efficiently and with less risk of damaging the prop or drive.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit make prop removal and installation easier?\u003c\/h3\u003e\n\u003cp\u003eThe wrenches are shaped to engage the splines and hub surfaces used on Volvo Penta Duo props, reducing slippage and the need for improvised tools. Their leverage geometry helps break seized nuts and cinch prop fittings to the correct seating without excess force. This saves time and lowers the chance of rounding fasteners or marring prop surfaces.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo dedicated tools sized for front and rear props to match factory fit.\u003c\/li\u003e\n  \u003cli\u003ePositive spline engagement reduces slippage during turning.\u003c\/li\u003e\n  \u003cli\u003eLeverage-focused design decreases effort needed to break tight fittings.\u003c\/li\u003e\n  \u003cli\u003eReplaces Volvo Penta part 3855516 for like-for-like service work.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat drives the durability and corrosion resistance of these tools?\u003c\/h3\u003e\n\u003cp\u003eThe kit is manufactured from heavy-duty carbon steel that is heat-treated for strength, then finished to resist rust. That combination provides the torque capacity needed for marine service while better resisting the corrosive environment around saltwater. Proper care—cleaning and light coating after use—extends service life further.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeat-treated carbon steel core for high tensile strength.\u003c\/li\u003e\n  \u003cli\u003eProtective finish to limit surface corrosion in marine settings.\u003c\/li\u003e\n  \u003cli\u003eSolid construction reduces risk of bending under load.\u003c\/li\u003e\n  \u003cli\u003eDurable edges retain correct fit to splines over repeated use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich Volvo Penta models and prop types are compatible?\u003c\/h3\u003e\n\u003cp\u003eThis prop wrench kit is intended for DPS drive duo propellers and fits DPS-A, DPS-B and DP-SM applications.

Use standard workshop torque procedures and an appropriate breaker bar or handle through the wrench opening. Avoid impact tools unless specified; use steady torque and check manufacturer torque specs for final tightening.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-piece prop tool set: front and rear specific wrenches included.\u003c\/li\u003e\n  \u003cli\u003eFits directly over prop hub splines for a secure turn when removing or installing.\u003c\/li\u003e\n  \u003cli\u003eUse with a compatible handle or breaker bar to apply controlled torque.\u003c\/li\u003e\n  \u003cli\u003eSupplied as a direct replacement for Volvo Penta 3855516.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Boat owners, marine technicians and DIYers who service Volvo Penta DPS duoprops and need an OEM-fit tool to remove and install D, F, FH, I and IH series props. It’s suited to routine maintenance, seasonal prop swaps and on-deck repairs where secure spline engagement and reliable leverage reduce the risk of damage to the prop or drive.
