SOLAS Amita 3 Aluminum 3-Blade Propeller 8.5x7 for Yamaha 6-8 HP

The SOLAS Amita 3 8.5x7 is a small-sized propeller, perfect for portable Yamaha 6-8 HP outboard engines (including compatible Parsun models and some Mercury/Mariner 6-8 HP that use the same spline shaft). This propeller is designed to get the most out of little engines by allowing them to spin up to optimal RPM quickly and propel a small boat efficiently.

With a diameter of 8 1/2 inches and a pitch of 7 inches, the prop puts minimal strain on the engine, which is crucial for 6-8 HP motors. In practical terms, this means your inflatable or dinghy will accelerate briskly without the engine struggling. The acceleration is smooth and the boat moves as soon as you hit the throttle, making it easier to carry an extra load (an additional person or gear) with no dramatic loss of speed.

When it comes to maneuvering – such as approaching a dock or anchoring – the SOLAS Amita 3 8.5x7 offers better control. The blades “bite” the water even at low RPM, so the boat responds more predictably to steering inputs. If you enjoy trolling for fish, this prop will maintain a steady very-low speed without the engine stalling or overheating.

The build is solid – the aluminum is cast using a high-tech process, which makes the propeller stronger than standard ones. Additionally, Solas applies a four-layer paint coating that shields the metal from saltwater and corrosion. This means even if you run your boat in the sea or leave it in the water for extended periods, the prop will remain in great shape.

Use Cases & Recommendations:

• Perfect for inflatable boats, small hard dinghies, and jon boats (2–4 m) – equipped with Yamaha 6 HP, 8 HP engines or their equivalents (e.g., Parsun 8hp, Mercury/Mariner 6-8hp that are Yamaha-based)
• Improved acceleration and lift: Allows small motors to get the boat moving quickly – useful when getting out of shallows or carrying extra load; the boat feels more agile and responsive
• Precise low-speed control: Excellent for trolling fishing – holds a steady slow speed around ~2-3 knots. Also aids in docking and maneuvering near shore, as it responds well to fine throttle adjustments
• Compatibility: Yamaha 6HP, 8HP two-stroke and four-stroke (8-spline prop shaft) from various years; Parsun 8 HP (Yamaha clone); certain Mercury/Mariner 6-8 HP models (co-produced with Yamaha). If your motor is from Yamaha’s 8-spline series, this prop will fit perfectly as a replacement for the OEM prop and generally corresponds to OEM part numbers (for example, Yamaha 6E0 or 6G1 series propellers)
