They also have other vendors. If you want to get the price down, get an alunimum prop. The stainless ones are much more expensive. For the minute extra performance, I don't see the advantage in them but I'm we'll enter a "religious war" debating the subject. barry Just sort of lurking in this conversation, but if a stainless prop and an aluminum one were exactly the same dimensionally, why would one perform differently than the other? Friction differences due to surface characteristics? |

Stainless is the way to go. -- Skipper |

Stainless : is the way to go. (I knew this would get started) In the comparison tests I've read (Trailerboats magazine) the speed advantage of Stainless was about 2 MPH. The cost premium was over 3X the cost of aluminum. So... the choice is yours but from my perspective (and I've had a boat for geez... over 40 years) I wasn't willing to pay the price premium for Stanless given the minute performance advantage.

Doug, no one would make a NiBrAl, brass, or SS prop with blades as thick as needed for the "same prop"(dia, pitch, area, shape) in aluminum, so you will never be able to make that comparison. A SS prop will be forgiving on logs & sandbars. Personal experience on our Glastron shows little difference in speed(SS slight advantage) but the SS is less prone to blow-outs and gives a better trim attide than the "same spec" aluminum. Polished SS props can be very pretty on your floating Camaro, too! Rob |

Friction differences due to surface characteristics? 1. Blade thickness. 2. Blade flex. The SS prop has the advantage in both categories and is therefore more efficient. The downside is that if you hit something you will end up doing some serious damage to your lower unit vs. an aluminum prop shedding part of its blades. |
