If we can stop breaking shafts the weakest link will then be the prop!!!!!

Hey Steve O, hope all is well with you sir... :)

Did we learn anything about these new prop shafts, new material???

Not yet, I've been too busy. I will get the info and am considering having a prop made with splines and no taper or keyway. Ron Hill says that would be no problem.

I'm guessing that not ALOT of folks haven't taken apart a brush hog gear box/T-blade mount but many use a tapered spline. I can't imagine that a prop could see any worse shock loads than my brush hog has seen (that is 25 years old) and has NEVER has been apart... THe shock of hitting a big stump or a basketball sized rock that is hiding in the tall grass with a brush hog is enough to shake your teeth out at the roots, and yet it stays together (they do have a dry clutch disk coupling on the gearbox output but are usually very rusty/crusty/TIGHT)...

Need to get the engineer from "Brush HOg" to do some moonlighting and tap into what he/they know... (fit/finish/clearances/material) ;)

I guess a taper/key design goes back a LONG LONG time to days where you wanted a shear to take place if there was too much force/shock/mud/rope/kelp/rocks impeding the prop...??? I dunno, just speculating... :)

Keep in touch Steve O... I'm looking forward to a visit with your crew at Long Beach which is JUST around the corner sir... I'm sure I will be grilling something so look me up (on the dark side of the stadium)... ;)

the only thing I've got to add on the whip strut is I have one on my Sanger mini both burgeon and Wilkes recommended it on that style boat
