Boat owners, listen up! If you're running a Mercury or Tohatsu 4HP, 5HP, or 6HP outboard motor, this 7.8x9 aluminum propeller is exactly what you need. The three-blade design gives you solid performance and durability without breaking the bank. Made from high-quality aluminum alloy that stands up to freshwater and saltwater use, though aluminum is always easier to repair than stainless steel if you hit something. The 12-spline design fits perfectly on compatible Mercury and Tohatsu engines from the late 80s onward. Installation is straightforward - just make sure you've got the right spline count for your motor. The black finish looks sharp and helps with corrosion resistance. Whether you're trolling for fish, cruising the lake, or just putting around the marina, this prop delivers reliable performance. Keep one as a spare or replace that damaged prop that's been affecting your motor's performance. Much more affordable than OEM but still built to last through seasons of use.
