Market Value Factors & Known Issues
| Factor | Description & Impact on Value |
| In-Mast Furling Jamming | Original Z-Spar / Z-Diffusion in-mast furling units require proper sail shape and batten tension to avoid jamming under loa. |
| Headliner Foam Separation | Deterioration of the foam backing behind the interior vinyl headliners leads to sagging in forward/aft cabins, requiring reupholstery. |
| Fixed Deck Portlights | Deck-integrated skylights and portlights require re-sealing over time. |
Propeller
| Part No. | Hull Number | Engine Option | Propeller | Price (2026) + Shipping |
| 033032 | 1 – 70 | YI YANMAR 4JH4AE 39KW(54HP) D | Fixed PROP 3 BL 18X12 RH30 E13 | $720.00 |
| 080364 | 70 – | YI YANMAR 4JH4AE 39KW(54HP)D | Fixed PROP 3 BL 18X12 RH30 51% ZF | $2,350.00 |
Fixed PROP 3 BL
- Type: 3-Blade Propeller
- Meaning: A standard fixed 3-blade marine propeller configuration designed to deliver a balance of thrust, speed, and efficiency for cruising sailboats.
18X12
- Dimensions: 18″ Diameter × 12″ Pitch
- 18″ Diameter: The overall width/circle diameter of the spinning blades.
- 12″ Pitch: The theoretical distance (in inches) the propeller moves forward through the water in one full 360° revolution.
RH30
- Rotation & Shaft Diameter: Right-Hand Rotation, 30 mm Metric Shaft
- RH (Right-Hand): Clockwise rotation when looking from behind the boat looking forward (standard forward direction).
- 30: Fits a 30 millimeter diameter propeller shaft (standard metric sizing common on Beneteau/European builds).
E13
- Hub or Specific Variant Designator: E13 Profile / Taper Code
- Meaning: Refers to the specific hub design, taper configuration, or proprietary foundry/manufacturer code (commonly associated with specific cone dimensions, keyway specs, or casting series like Radice/Bruntons or specific Beneteau OEM sourcing codes).
- E13 refers to the E13 model series by the Italian manufacturer Eliche Radice, a major OEM propeller supplier for Beneteau, Jeanneau, and other European boatbuilders.
- Key technical specifications defined by the Radice Type E13 designation include:
- Taper Ratio: 1:10 Standard ISO/Metric Taper (for every 10 units of length along the shaft cone, the diameter decreases by 1 unit).
- Blade Geometry: 3-blade fixed bronze propeller designed for low hydrodynamic resistance under sail while providing solid displacement thrust when motoring.
- Keyway Standard: Metric keyway dimensions matched to ISO 4566 standards for 25 mm, 30 mm, or 35 mm shafting.
51%
- Expanded Area Ratio (EAR / DAR): 51% Blade Area Ratio
- Meaning: The total surface area of all blades covers 51% of the full circle defined by the propeller’s outer diameter. This ratio is tailored to prevent cavitation while keeping hydrodynamic drag low under sail.
ZF
- Manufacturer / Pattern: ZF Marine
- Meaning: Manufactured by or built to the profile specs of ZF Marine, a major global provider of marine propulsion and underwater hardware.
Beneteau Oceanis 40 Q & A
Question:
Our SailDrive is gone on our 2012 Beneteau Oceanis 40 . It was a SD50 serial number 0305-12. To replace it I need to know :
- Is it a long or standard length shaft?
- What is the gear ratio?
I want to replace it with an SD60.
Answer:
1. Shaft Length (Leg Length)
Your 2012 Beneteau Oceanis 40 with a Yanmar SD50 uses a Standard Shaft Length.
- Standard Leg Length: ~395 mm (15.5 inches) from the mounting bed to the propeller centerline.
- Long Leg: Extended legs (such as the +58 mm or +100 mm options) are typically reserved for deep displacement hulls, custom powerboats, or multi-hulls with high engine beds. Beneteau builds the engine bed in the Oceanis 40 specifically to accept the standard-reach drive.
2. Gear Ratio
The standard gear ratio for the Yanmar SD50 paired with the Yanmar 3JH / 4JH series engines used on the Oceanis 40 is 2.32:1 (ahead and astern).
- SD50 Ratio: 2.32:1
- SD60 Replacement Ratios: The Yanmar SD60 is available in 2.23:1 or 2.49:1.
If you choose the 2.49:1 ratio, you may need to adjust your propeller pitch.
When upgrading from the SD50 to the SD60, most owners choose the 2.23:1 ratio to keep their existing propeller setup as close to identical performance as possible.
