Excellent upgrade for all 300/310 Jet Skis, reflash needed to take full advantage 

109mm pulley can go on any ski, and is a cheaper replacement option than genuine. Slight boost increase.

108mm pulley is race spec. You MUST run fresh (3months old MAX) 98octane fuel (Australia) or 93 Octane (USA) with this pulley. It will also come with a new idler to reduce belt slack. More significant boost increase.
