Its extended length allows custom pump pressure tuning, resulting in additional thrust — higher top speeds, better acceleration and reduced cavitation. Adjustment is simple: remove the stainless steel tail cone bolt, pull off the billet cone, and add or remove the supplied spacers (3mm, 4mm and 5mm included; other thicknesses available separately). Choose the cone for your pump below.\u003c\/p\u003e\u003ch3\u003eChoose Your Cone\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eYamaha SVHO (part # L13-YAM-SVHO).\u003c\/strong\u003e For use with the OEM SVHO pump only.
