Re: Stus-List Geared folding props

[Charles Nelson via CnC-List]

I 2nd the Gori 2 blade geared folding prop:

Lowest drag of ANY prop by experiments reported in Yachting a few years ago.

Detailed recommendation of pitch and diameter after boat owner supplied info on 
engine, trains ratio and boat displacement.

Cost was comparable to other props with experimentally measured higher drag, 
even if only marginally higher.

Geoff at AB Marine very knowledgeable and helpful in prop selection--he is a 
New Zealander so don't say he has an English or Australian accent!

Issues in reverse same as other geared, folding props.

Enough forward force to drive my boat at hull speed.

I service it at yearly haul-outs (inspect, clean, lubricate) and, like the 
Energizer bunny, it keeps on going and going, etc.

No connection with company but a very satisfied customer.

Re: Stus-List Geared folding props

[Randy Stafford via CnC-List]

No.  But my boat is only in the water (fresh water at that) for seven months at 
a time.

However one calm day last summer I eased her into a shallow cove so I could 
clean her bottom while standing on the lake bottom.  I realized too late I was 
in an area of grasses / algae / vegetation.  When I went to motor back to the 
marina, the prop was fouled and wouldn’t open all the way.  Once I was finally 
back in my slip after a very inefficient half hour of motoring, I dove the boat 
to unfoul the prop.  No fishing line or anything involved, just a bunch of 
vegetation wrapped around it and stuck in the gears.

I have a Gori folding prop (geared).  I grease the gear teeth with marine 
grease every launch.

Cheers,
Randy

I have a Gori 2 blade and no, no issues.  Fresh water boat though we (though 
not i, yet) do get zebra mussels and algae etc.
Happy with it, forward and reverse.

Flex-o-fold, no issues opening in forward, a quick shot of power opens fine in 
reverse, less prop walk than the fixed 2 blades it replaced.

OK, you all know I have a Martec on Touche' and, for the most part, am 
satisfied with it.  However, if I did change, my inclination would be to 
replace it with a geared 2 blade folder.  Especially since I think Martec 
doesn't make non-geared folders anymore.

I have a SPECIFIC question for those who have a geared 2 blade folder.

With your geared 2 blade folder, have any of you noticed a failure to fully 
open or close due to marine growth in the gears?

[Matthew L. Wolford via CnC-List]

Flex-o-fold, and no.  However: a) I’ve only had mine on for one season; b) I 
noticed at the end of the season that it did not open and close as smoothly as 
it did when first installed (although it appeared to be working fine); and c) 
I’m on Lake Erie, so my marine growth is not the same as yours.
