🔧 Product Description

Genuine Volvo Penta 3-blade fixed aluminium propeller, 15 x 12 in, for the Volvo Penta saildrives 110S, 120S, MS25S, 130S and 150S. Volvo Penta fixed propellers are exclusively designed for Volvo Penta saildrives. They are manufactured in high-quality, durable aluminium alloy developed to withstand corrosion and cavitation damage, with a rubber bushing in the hub that minimizes stress on the drivetrain caused by gear changes, and an epoxy coating that is highly resistant to abrasion. Available for left-hand rotation in multiple sizes and pitches.

🔌 Function

Generates thrust from the drive's rotation, the 15 inch diameter working a larger disc of water than the 14 inch wheels at a similar pitch.

⚠️ Common Signs of Failure

• Vibration through the hull that tracks propeller speed
• Reduced top speed or poor acceleration onto the plane
• Engine over-revving with the boat not responding, indicating hub slip
• Bent, chipped or partly missing blades
• Roughened, pitted blade faces from cavitation

🛠️ Service Notes

• The 15 x 13 propeller 23478965 is within five grams of this one at 2.436 kg, so the stamped pitch rather than the weight identifies it
• Check the anodes on the drive leg while the propeller is off
• Installation hardware for the fixed propellers on 110S, 120S, MS25S, 130S and 150S: propeller cone kit 23749222, which includes screw 23748333 and lock washer 23680979.
