So they are respected until they test the prop you hate? What does Unicorn taste like?
All kidding aside, haters gotta hate
I don’t hate the prop. It’s not the props fault. Just want a fair comparison. But it’s clearly aimed at the guys who just don’t know any better…when you getting one ?

I think if I want my model T fixed I will call you. If my Tesla breaks probably not.

I for one, am just glad there are people out there pushing the envelope and trying new designs. It would be nice if we could get a fully instrumented before and after set of data for this one, fuel burn/gps mph at various rpm points, for example. Run that collection setup on a boat, then swap the prop and repeat. Shouldn't be that hard to do. Or to then run whatever gains are realized(if any) against an ROI calc.

An outfit that 'Reviews' Products, and has Never found Everything they test to be less than Excellent, has been shoveling Manure over this Prop for 2 or so years. Time will tell whether this Pretzel is any better than what is out there now. They are a One Strike Prop, as repairs to return it to even sort of 'Good as New' are not possible. I sure some Pigeon will buy it and then when it isn't what the Hype said it would be, would still say it is great, just so he/she doesn't reveal they were had.

Well youngster I remember when all those things were said about stainless props.

I ran the numbers quoted on a prop slip calculator. The sharrow showed an impossible number. The 5 blade showed a just ridiculous 30% slip. I’ve never known anyone to have a prop slip like that. Not unless it’s a sailing boat or displacement speed slip number.
Someone is telling lies on the test result data. Such a shame. Insulting too, that they assume the consumer is so stupid. Longing for a fair test. If it’s good…great. But so far…it’s all been make believe.

There was very little fake promotion of Stainless, as Bronze was already an alternate to Aluminium.
Well youngster I remember people saying how stainless was to hard to fix. Would wreck lower units and be not worth the money.

For a guy with a Unicorn you sure don't believe in much.

well, in all honesty, stainless is much harder to fix compared to Aluminum or Bronze. Requires special procedures for welding, whereas the other two are relatively easy and soft to work with. This goes with "wrecking lower units" if you hit something with an aluminum or bronze prop, the prop will absorb more of the impact vs transmitting it to the lower unit, and wrecking the internals. As for corrosion resistance, Aluminum and Bronze are further over on the galvanic scale than Stainless, so, instead of the prop being sacrificial, now your aluminum lower casting is...... a little science goes a long way, and with corrosion, good anodes go a good bit further.....

as for this prop, the design of it is what is going to make it non economically repairable. I can guarantee that your local prop shop wouldnt touch it with a 10 foot pole. You cant just bang this thing back into shape with a 24oz framing hammer and call it "good enough" like has been done for years with standard designs....

actually, I do. However I dont have a TIG setup to work with either Aluminum or Stainless. I do know that if you overheat stainless, you can burn out the alloy and remove the stainless qualities of it. Aluminum just ends up as a molten hunk on the floor if you do it wrong. Myself I stick to mild steel.

Thank you for mansplaining to me.

Why do you need Tig to weld stainless? I am pretty sure you can weld stainless with stick
you absolutely can weld stainless with stick, gas or wire feed, however TIG allows you much greater control of your puddle, heat, and of course shielding gases when working with materials that can be quite finicky,

Maybe that is why we don't see many Stainless Props for Small Outboards.

Stainless and Bronze are Heavier and can increase Wear on the Clutch Dogs and Gears, if the Operator "Eases" it into/out of gear.
I do know that with a Stainless, an Impact will very often bend the Prophaft. In 2002, I put my RAKER on the O/I and with less than 10 hrs on it, bent the Prophaft. Dealer was great, he had one of the Mechanics put the Parts out of a New Unit in the Showroom, and had me boating again in 2 days.
