This is your right-off-throttle \"bottom end\" hit. The trailing edge is what will carry you through the power band and allow the engine to get the full amount of power to the water.\u003cem\u003e People often don't realize it, but impeller tuning is just as important, if not more, than carburetor tuning. \u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003ePart Number: IMY148-9\/15, IMY148-10\/16, IMY148-11\/17\u003c\/p\u003e","brand":"Impros","offers":[{"title":"9\/15","offer_id":48413214245019,"sku":"30-IMY148-9\/15","price":435.0,"currency_code":"USD","in_stock":false},{"title":"10\/16","offer_id":48413214277787,"sku":"30-IMY148-10\/16","price":435.0,"currency_code":"USD","in_stock":false},{"title":"11\/17","offer_id":48413214310555,"sku":"30-IMY148-11\/17","price":435.0,"currency_code":"USD","in_stock":false},{"title":"Custom Pitch (special order)","offer_id":48413214343323,"sku":"30-IMY148-CUSTOM","price":510.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0318\/7507\/2133\/files\/ImprosImpeller2S144-160mmSTD_1.png?v=1782676681","url":"https:\/\/highspeedind.com\/cs\/products\/impros-hooker-yamaha-2s-148mm-impeller","provider":"High Speed Industries","version":"1.0","type":"link"}
