Boat owners, listen up - if you're running a Mercury or Tohatsu outboard between 8-9.9HP, this 8.5x8.5 stainless steel propeller might be exactly what you need. The specs are straightforward: 8.5-inch diameter, 8.5-inch pitch, right-hand rotation, with a 12-tooth spline that fits specific models perfectly. Now, compatibility is key here - it works with Mercury/Tohatsu 2-1/2\ gearcase models including 8/9.9hp (4 stroke) from 2005 onward, 8hp (2 & 4 stroke) from 2005 onward, 9.8hp (2 & 4 stroke) from 2005 onward, plus MFS8/9.8 and NSF8/9.8 models from all years. This is an aftermarket product, but the quality is solid - stainless steel construction means better durability and performance compared to aluminum props. Before you order, definitely double-check your current propeller's brand, diameter, pitch, and spline tooth count to ensure compatibility. The 8.5x8.5 size is pretty common for these horsepower ranges, providing good acceleration and top speed balance for various boating applications. Stainless steel props like this one typically offer better performance in terms of speed and fuel efficiency compared to aluminum, and they're more resistant to damage from debris in the water. The craftsmanship looks good - the blades are well-formed and the finish is smooth, which helps with water flow and efficiency. If you do run into any issues or have questions about compatibility, the seller encourages reaching out, which is always reassuring with marine parts. Whether you're replacing a damaged prop, upgrading from aluminum, or just keeping a spare on board for emergencies, this propeller delivers reliable performance at a more reasonable price than OEM options. For serious boaters who understand how propeller specifications affect performance, having the right prop makes all the difference in how your boat handles, planes, and performs across different loading conditions.
