From Propeller Guard Information Center
MagBlade MaxThrust & SlipStream Propellers Brings Safety to Boat Propellers :: Propeller Guard Information Center

"Mag Blade is manufactured from a keronite (ceramic) coated Thixomolded magnesium alloy. The use of Thixomodling [sic], somewhat similar to plastic injection molding, results in a near net shape product."



Read the entire report; it's actually pretty interesting. (Not saying I believe it all, I just found it interesting.)

Indeed.

I would also offer the high level thought (re. the safety aspect) that any spinning edge doing 800+ rpm, no matter how blunt - in a metal (or polymer) witgh HP dtiving it vs human flesh scenario - the prop is going to win every time. (How else does a strimmer work?)

Whether it improves fuel efficiency or not I will be very interested to see. Bring on the back - to back testing.....

Would like to see some back to back testing of these things - can't see how you can get that much more performance though ...........

Right, I've got my drill and a tin of red paint - off to transform my standard prop! I guess if I drill enough holes it will be 30% lighter when I've finished

Do you know the correct way to drill the holes?

I drilled some holes in a rather heavy Vance and Hines exhaust pipe on a racing bike once - thinking the lighter weight might me an advantage in a race. The bike unsurprisingly went a lot slower - but with a magnificent backfire on odd occasions - scared the s**t out of any opposition close by however!

It was pretty interesting. I am pretty damn skeptical of how they are going to address corrosion of magnesium in salt water. Magnesium is currently used for anodes on some freshwater boats since its far more reactive than zinc and thus protects Ali parts (like outdrives...) far better.

Not sure if a ceramic coated magnesium prop will actually work long term - especially in salt water.
