Speed Nut for 5/8 shaft for the Tohatsu 60/40 Jet Outboard

Engineered to unlock the snappy acceleration your jet outboard deserves. This Speed Nut replaces the stock impeller nut on your Tohatsu 60/40, using a precision spiral cone design that streamlines water flow to the impeller. Where the factory nut creates turbulence, this one smooths the path — reducing cavitation and noise while delivering the holeshot advantage that matters most when you're loaded heavy or fighting tough conditions. It's a small refinement that compounds into real on-water performance: quicker to plane, sharper response off the line. Another gear in your arsenal to extract every ounce from your jet.
