Mercury Marine Qualifies for Free Shipping Mercury Propshaft Inner Fits Bravo III #865322T
Mercury Marine Mercury Propshaft Inner Fits Bravo III #865322T $1,769.49
Mercury Marine 865322T Prop Shafts The Bravo III is a counter-rotating dual-prop drive, and the inner propshaft is what makes that system work. It carries the forward prop, transmits torque from the drive, and has to do all of that while staying in precise alignment with the outer shaft under load. When the inner shaft is bent, worn, or damaged from a strike or bearing failure, the whole drive suffers — vibration, prop walk, and accelerated wear on seals and bearings are all symptoms of a shaft that's past its service life. The #865322T is a genuine Mercury OEM Inner Propshaft for the Bravo III. At over 8.5 pounds of precision-machined steel, this is a heavy-duty component built to Mercury's exact dimensional and metallurgical specs. Fit and balance tolerances on a propshaft are critical — even minor deviations translate directly into vibration and premature wear on the drive. Genuine Mercury construction means you're getting a shaft that's right, not just close. Bravo III drives are found on serious performance and offshore boats, and the owners who run them know the difference between doing a repair right and doing it twice. If you've had a prop strike, are rebuilding a drive, or are chasing vibration that won't go away, the inner propshaft is often the culprit. Normalized SKU: 865322TUPC Code: 745061589391

Mercury Marine Mercury Propshaft #840377T $0.00 $1,394.40
Mercury Marine 840377T Prop Shafts A bent or worn propshaft doesn't just kill performance — it puts stress on your gearcase, bearings, and seals every time you run the engine. If you're chasing a vibration that won't go away or dealing with a shaft that took a hit, the Mercury Marine Propshaft #840377T is the OEM replacement built to bring your outboard back to factory spec. This is a genuine Mercury Marine part, not an aftermarket substitute. When you're talking about a component that spins at thousands of RPM and transfers all of your engine's torque to the propeller, fit and metallurgy matter. OEM shafts are machined to the exact tolerances Mercury engineers designed the gearcase around — which means proper prop seating, correct spline engagement, and no surprises once you're back on the water. At just under 7 lbs, the 840377T is a substantial shaft suited for larger Mercury outboard applications. If you're unsure whether this is the correct shaft for your engine, cross-reference your serial number with Mercury's parts catalog or give us a call at 816-841-3364 — we're happy to help confirm fitment before you order. Genuine OEM Mercury Marine propshaft — not aftermarket Machined to factory tolerances for proper gearcase fit Correct spline engagement for secure propeller seating Resolves vibration caused by bent or damaged shafts Weight: ~6.8 lbs Normalized SKU: 840377TUPC Code: 745061396562
