Twister Nut
For those who want to get every last bit of performance gain from their outboard jet pump. The twister nut replaces the standard impeller retaining nut. The tapered cone streamlines waterflow to the impeller as opposed to a standard nut which in some cases can cause water disturbance. Top speed gains are very minimal (less than 1km) with the main benefit being improved holeshot. 
Please Note,
The twister nut is intended for fine tuning and wont make up for an underpowered engine. The standard locking washer with bend over tabs is still required to be used with the twister nut.
