hi i had posted a while back about my 19 ft bow ridernot getting up on plane. well i tested out all the manuale trim positions and found the sweet spot and now it does about 33mph on a good day in the bay. but im looking for a little more top end speed and bow lift. im currently runin a 13.25X17 and i think i should be riding a 13.50X20or21 <br />right now the boat ive got is realy light but gets no bow lift at top speed. what do you all think should i gety this prop or no<br /><br />give me some numebrs on prop sizes you recomend
