propellers with leading edge roll/cup ?

[Ron Hill]

So is this face cup the opposite of doing a Texas cut?
I have a slt boat a good Texas cut prop runs real good . Rons face cup props drag there arse a bit out of the hole and top end. Trimmed the face cup off one and picked up 3 kph and better hole shot ??
If you got the dollars just buy a genuine merc clever can't beat them .

The "Texas Cut" came about from too much "FACE CUP", so we cut some off it and my dad said, "Oh, that's called a 'Texas Cut' but no one in Texas had heard about it."

The first "Texas Cut" I every made was on a Mercury Offshore prop for an SJ.

SRX on my own . Taken out leading edge cup and trailing edge cup.

Sorry but your wording on the parts of the prop is not correct.
On the prop you show above there is added trailing edge cup and added tip cup. a fair amount of tip cup and looks pretty good.
there is no leading edge difference to normal srx.

the work done on your prop would add maybe 1 inch in pitch, and 1/4 inch less diameter . so now about 13.5 x 24..
you might be able to spin that to about 6500 with your new mods to your motor.


The LEADING EDGE is from the bottom of the hub going up to the tip.

as shown in pic below on my srx. the is prop was not altered from new apart from polishing.

Okay,
Ive bent LEADING edge away from the nut, "derolled" made trailing edge cup SMALLER with TIGHTER cup radius than stock SRX.

Its good You know what Ive done. I dont have to tell that. Yes and also how it works. We have language barrier here, You speak english, I finnish .
PS. photos do lie

yes sometimes the language barrier can be a problem, not only Finnish to English, but even English UK to English USA can also be very different.

but yes I can see you have put a nice cup in the tip, this will lift the bow much better. you have good skill with bending the prop nice.
I need to try this with my srx too.

if I can get the leading edge cupped and the tip cupped on srx it might just be the ideal prop for my boat.
I need more bite from start and a bow lift like a raker prop. but as you know in the uk and Europe no good price props are available, all too expensive.

and yes photo's do lie a lot on computer. I cannot get good picture os my 13x17, it looks realy bad in picture, but in real life it is very nice.
