I'm adding a SS prop to my 5.0 OMC Four Winns 21.5 Sundowner. Should I expect a performance difference? Same Diameter and Pitch. I don't think so, but the guy I'm buying it from says you a get a bit more speed out of it. Any comments out there?

Re: SS Props

Yep, just alittle speed and a little more durability when it comes to touching the bottom. but ss does not give like al. there are pros and cons on this issue I have a 205 sundowner and elected to keep al props. easy to replace if I get into the muck.<br /><br />scott :p

Re: SS Props

NORMALLY - the same style (cupped, uncupped, etc.), same number of blades, same diameter, same pitch will give you slightly more speed in a stainless prop. But not always, according to other posters here. (It has helped me on 3 different boats though)<br /><br />Also, contrary to popular belief, a SS prop isn't necessarily bad if you hit bottom. They weigh much more, and they will usually cut through stuff better than an aluminum prop will, and not get damaged. They also have a rubber insert in them that will spin if you hit something really hard. <br /><br />It's like hitting a softball with a light bat or a heavy bat. The lighter AL prop will transmit more energy into the lower unit, according to the prop shops that I have talked to.<br /><br />And, as a recent witness to this, I hit an oyster bar with my SS prop 2 weekends ago (Wachapreague flats), and only polished my skeg. It would have wiped out an AL prop.
