Yamaha’s 30hp outboard spans two very different eras — the older 2-stroke (10-tooth spline gearcase, sold 1983-2002) and the current F30 4-stroke (13-tooth spline). A propeller sized right for one won’t fit the other, so confirm your gearcase spline count against the part listing before ordering. These five props cover the genuine Yamaha OEM part plus the aftermarket brands (Solas, PowerTech, Turning Point) that make direct-fit aluminum and stainless options for the 20-30hp Yamaha range.

The picks, in detail
Yamaha OEM G-Series Propeller 6H5-45945-00-00
The genuine Yamaha aluminum 3-blade prop for the current 13-tooth-spline gearcase, shared across the F30/F40/F50/F60 4-stroke family — the correct factory replacement for a modern F30.
- 10.375″ diameter x 13″ pitch, 3-blade aluminum
- 13-tooth spline, RH rotation
- Fits F30/F40/F50/F60 4-stroke gearcases
- Guaranteed exact factory fitment for the current F30
- No compatibility guesswork versus aftermarket cross-references
- Higher price than aftermarket aluminum equivalents
- Wrong fit entirely for the older 2-stroke 10-spline 30hp
Solas Amita 3 Aluminum Propeller
A well-established aftermarket aluminum 3-blade prop line, sold in multiple pitches specifically rated for Yamaha’s 20-30hp range, covering both the older 2-stroke and newer 4-stroke gearcases depending on the exact SKU.
- Multiple pitch options (9″-15″) for the 20-30hp Yamaha range
- 3-blade aluminum construction
- Available for both 7-spline (older 2-stroke) and 10/13-spline gearcases
- Lower cost than Yamaha OEM
- Wide pitch selection to tune top speed vs. acceleration
- Must match spline count and diameter to your specific gearcase generation
- Aluminum wears faster than stainless under heavy use
PowerTech Aluminum Propeller (ILB3/SRA3 series)
PowerTech’s aluminum prop line for the Yamaha 20-30hp range, positioned as a performance-oriented alternative to the stock Solas/Yamaha profile with a cupped blade design.
- Rated for Yamaha 20-30hp gearcases
- Cupped blade design
- Multiple pitch options available
- Performance-tuned rake/cup versus a generic replacement prop
- Competitive pricing versus Yamaha OEM
- Less brand recognition than Solas among casual boaters
- Confirm exact spline/diameter match before ordering
Turning Point Hustler 10.375 x 13 Aluminum Propeller
A widely-stocked aluminum 3-blade prop rated across a broad 9.9-35hp range, sized to match the current F30’s 10.375″ diameter.
- 10.375″ diameter, 13″ pitch, 3-blade
- Rated for 9.9-35hp outboards
- Stainless-steel-tuned rake angle at an aluminum price
- Broad horsepower rating gives fitment flexibility across similar Yamaha models
- Widely available through marine retailers
- Still must be matched to the correct spline count for your gearcase generation
- Mid-pack pricing — not the cheapest aluminum option
PowerTech SRA3 Stainless Steel Propeller
PowerTech’s stainless-steel prop for the Yamaha 20-30hp range, for owners who’ve decided the durability and rigidity of stainless is worth the price jump over aluminum.
- Rated for Yamaha 20-30hp gearcases
- Stainless steel construction
- Cupped, high-performance rake angle
- Stainless resists bending/damage far better than aluminum on rocky or shallow water
- Stiffer blades hold their shape better at speed, improving efficiency
- Roughly 2-3x the price of the aluminum options in this list
- Overkill for casual, careful use in clear water
Buying tips
- Confirm your gearcase generation before buying anything: the 1983-2002 2-stroke Yamaha 30hp uses a 10-tooth spline, while the current F30 4-stroke uses 13-tooth spline — the same nominal “30hp” name covers two incompatible prop shafts.
- A lower pitch trades top speed for faster acceleration and better hole-shot (useful loaded down or pulling a tube); a higher pitch does the opposite — most direct-fit props like these are offered across a pitch range for exactly this reason.
- Aluminum is the sensible default for most owners — it’s cheaper to replace after hitting something. Only step up to stainless (like the PowerTech SRA3) if you’re chasing every bit of efficiency or running in debris-prone water where you’re not worried about denting a spendy prop.
