I'm considering getting a SS prop for my Yamaha F115 on a 19" Yamarin cabin boat, weighing ~1600#, <br />Currently running an Yamaha K13x19, which works pretty well, except I'd like some more bow lift and better grip in the water. <br />With 2 persons in the boat I'm getting a tad over 40mph @ 5700 rpms. Max rpm for that motor is listed as 6000. <br /><br />Any comments on these props currently on sale on iBoats, handling characteristics/differences to be aware of? <br /><br />And BTW, the Hustler/Express props, do they come with hub kit or is that sold separate?
