The 3.0L Volvo Penta engine runs an SX sterndrive (the same lower unit as the OMC/Cobra SX), so the correct props are sold under “Volvo Penta SX” or “OMC/Cobra SX” fitment rather than by engine displacement alone. Below is a real spread across the fitment axis that matters here — OEM aluminum, aftermarket aluminum, and stainless upgrades in both 3- and 4-blade — not just “more props.”

The picks, in detail
OEM Volvo Penta SX 3-Blade Aluminum Propeller (14.5×19 RH, PN 3817468)
The factory-spec aluminum 3-blade for the SX drive, the safe default replacement if you’re matching what came on the boat originally.
- 14.5″ diameter x 19″ pitch, right-hand
- 3-blade aluminum
- OEM Volvo Penta part 3817468
- Guaranteed correct OEM fitment
- Aluminum is cheaper to replace if you strike something
- Aluminum flexes more under load than stainless, costing some top-end performance
OEM Volvo Penta SX 4-Blade Aluminum Propeller (14×21 RH, PN 3587524)
The factory 4-blade alternative, trading a bit of top speed for better hole-shot and a smoother ride — a common swap for boats that plane slowly or carry heavy loads.
- 14″ diameter x 21″ pitch, right-hand
- 4-blade aluminum
- OEM Volvo Penta part 3587524
- Better acceleration and low-speed handling than the 3-blade
- Still factory OEM fitment
- Slightly lower top speed than the 3-blade equivalent
Michigan Wheel Michigan Match 14-1/4×21 RH (Volvo SX/Cobra SX, PN 161004)
An aftermarket aluminum 3-blade built specifically to Volvo SX/Cobra SX fitment, a common step-up choice from OEM aluminum for buyers who want a name-brand aftermarket option without going stainless.
- 14-1/4″ diameter x 21″ pitch
- 3-blade aluminum
- Direct Volvo SX / Cobra SX fitment
- Well-regarded aftermarket brand
- Direct fitment, no adapter needed
- Costs more than the equivalent OEM aluminum prop
Solas Hydro Aluminum Propeller for Volvo Penta SX
A budget-friendly aluminum aftermarket option in the same fitment family, sold across a 15″-21″ pitch range so you can dial in the pitch for your boat’s load and top speed.
- 13.75″-14.5″ diameter
- Pitch options from 15″ to 21″
- Direct Volvo Penta SX fitment
- Lower price than Michigan Wheel or OEM for a comparable aluminum prop
- Wide pitch selection to fine-tune performance
- Aluminum construction, same flex tradeoff as the OEM options
Solas Amita/Stainless Propeller for Volvo Penta SX
Solas’s stainless step-up for the SX drive — stiffer blades than aluminum mean less flex at high RPM and noticeably crisper acceleration.
- Stainless steel construction
- Volvo Penta SX fitment
- Multiple pitch options
- Stiffer blades improve high-RPM performance versus aluminum
- More resistant to bending on minor strikes
- Costs meaningfully more than any aluminum option in this list
PowerTech REV4 Stainless Propeller (Volvo Penta SX)
A 4-blade performance stainless prop, 14.6″ diameter across a 16-24 pitch range, aimed at buyers chasing the best acceleration and hole-shot the SX drive can deliver.
- 14.6″ diameter
- 16-24 pitch range
- 4-blade stainless steel
- Strong reputation for hole-shot and mid-range acceleration
- Wide pitch range for tuning
- Among the priciest options for this drive
HR Titan 4 (Solas) Propeller for OMC/Volvo Penta SX
A 4-blade stainless prop from Solas’s HR Titan line, sold across multiple pitches for the same OMC/Volvo Penta SX fitment as the props above.
- 4-blade stainless
- Multiple pitch options (14.25″-14″ diameter range)
- OMC/Volvo Penta SX fitment
- 4-blade stability at a lower price than PowerTech’s REV4
- Same fitment family as the other SX props here
- Less widely reviewed than the Michigan Wheel or PowerTech names
Buying tips
- Confirm your drive is the SX lower unit before ordering — Volvo Penta’s 3.0L was paired with the SX drive, and props are sold by drive fitment, not engine size.
- Aluminum (OEM, Michigan Match, Solas Hydro) is the right call if you run in shallow or rocky water where you might strike bottom; stainless (Solas Amita, PowerTech, HR Titan) is worth it once you’re chasing top speed or hole-shot on clean water.
- Going from 3-blade to 4-blade generally trades a little top speed for better low-speed handling and a smoother ride — matters most if the boat is heavily loaded or planes slowly.
