Solas Amita 3 Aluminum 3-Blade Propeller 8.5x7 for Tohatsu 8-10 HP

The Solas Amita 3 8.5x7 is engineered to boost the performance of your small outboard. If you have an inflatable dinghy, a small fishing boat, or a tender powered by a Tohatsu 8-9.8 HP (or Mercury/Mariner 9.9 HP, which often share the same prop), this aluminum prop will noticeably improve your on-water experience. With a diameter of 8.5″ (215 mm) and a pitch of 7″ (178 mm), the propeller allows the engine to spin up quickly and pop the boat onto plane with minimal delay.

The 7″ pitch is on the lower side, meaning it’s tuned to provide maximum thrust and acceleration – valuable for slower craft or heavily loaded small boats. This makes the Amita 3 8.5x7 a great choice if your boat struggles to plane with the factory prop or if you want more punch out of the hole. Furthermore, the three-blade design is standard for this horsepower range, ensuring a familiar, predictable feel but with greater strength and quality than many OEM props.

Suitable Boats & Conditions:

• Inflatables and Tenders: Perfect for 2.5–4 meter inflatable RIBs or soft-bottom dinghies equipped with 8-10 HP engines. It helps you achieve better speed with a small boat, which can be critical when carrying an extra person or dealing with choppy conditions.
• Small Jon Boats: On aluminum or plastic jon boats with low-power outboards, this propeller makes it easier to move against current or through shallow waters. The engine will operate more comfortably since it can reach the needed RPM without undue strain.
• Auxiliary Sailboat Motors: If you use an 8-9.9 HP outboard as an auxiliary on a sailboat, the Solas Amita 3 8.5x7 provides reliable thrust for harbor maneuvering and docking. The low pitch delivers strong push even at slow speeds – important for control when guiding a sailboat into a slip.
• Upgrade from Plastic or Worn Props: Many small engines come with plastic or lower-grade props. Upgrading to a Solas aluminum prop increases resistance to damage (such as nicks or cracking) and can improve overall efficiency. The Amita 3 8.5x7 is made with a squeeze-cast process that gives its blades extra strength.
• Easy Installation & Compatibility: This prop fits directly on 8-10 HP Tohatsu, Mercury, Nissan (and Parsun) engines with the appropriate spline or pin drive (depending on model – most 8-9.9 HP have 8 or 9 splines). Check compatibility if unsure, but Solas designs this as a broadly compatible solution for the mentioned brands. Installation is straightforward and you’ll immediately notice improved thrust and responsiveness.
