online place (not ebay)? Also looking for yamaha accessories like speedometer, fuel gage and
such .. any idea for that? Thanks, Matt |

from them at a very good price. 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 steel is STIFFER than the aluminum prop and will outperform
it. Also, aluminum props ding up much easier than steel props. Stainless
is the way to go. --

| Identically dimensioned aluminum and stainless props will perform about
the same under identical circumstances for most boaters. If you are
pushing a 21' fishboat with a 200 hp outboard, and you have two props,
one alum and the other stainless, and they have the same pitch, diameter
and blade geometry, the performance will be about the same. Different
cup design, very high speed boat, et cetera, and thinner blades
available on a stainless prop might make a difference. What would an ersatz Skipper know when the real Skipper never owned a boat? |

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. (I'll bow out of the now) barry |

| No need to bow out. I'll not be arguing with the grizzled putz. Most
know he issues his childish gibberish counterpose just to troll. He does
not respect truth or the original requesters question. BTW, when I was racing C stock hydros back 50 years ago you didn't see
many aluminum props on racing boats of ANY class. The physics of the
damn twirly things haven't changed all that much since. You go with
stainless for PERFORMANCE advantages. --

| I'll bet the geometry and cup design of the alum and stainless props
were different. Any comparison I've ever read of alum vs. stainless
props showed virtually NO difference if the diameter, pitch and cup
dimensions were nearly identical. If your boat does 35 mph at WOT with an alum prop and 36.9 mph with a
stainless prop, and the stainless prop costs $250 more than the alum
prop, then anyone with a working brain would pass up spending more than
is necessary. At cruising speeds, the speed differences would probably
been even smaller. Stainless props have their place, but not necessarily as a way to
improve speed, not for the typical boater. Oh...if you hit something with an alum prop, you'll likely break a
blade. If you hit something with a stainless prop, you may do one heck
of a lot more damage to the prop shaft and its attached gearing. |

| Please - take no offense, but try Google and look around. You will be well and truly amazed. |
