Expanding on Curtis' post, I have a geared Flexofold (just been delivered - 3
days Denmark to Calgary - I’m impressed) I assume, as the blades are geared
together, that blade position doesn't matter - yes?

Thanks that helps. Good Idea. I plan to dive this weekend to put the Zink on
the shaft I will Market then.
Thanks again.

Curtis,
I put it in reverse and it closes right up. For racing, I have the shaft
marked for when the blades are horizontal, so when I put the boat in gear they
fold best. Otherwise, when vertical, the lower one my drop (gravity is a
bitch).
All the best,
Edd

When sailing how do I get the prop in the correct position or collapsed.
Do I put the transmission in rev? I have a 2 blad mertec folder prop and a
2gm20F Yanmay and a Kenzaki KM2P transmission?

I had a 29-2 for 10 years. It is actually a 28.5 foot boat with a 13
hp engine. I used a martec folding prop and it worked fine. If I were going
to a new prop kiwi props are lighter, less drag and will outperform the heavy
brass bronze props made by Gori, Flexofold, etc. They are also more
economical and adjustable. A friend put one on his Sweden 38 and he raves
about it. Jerry. C&C 27-v.

I’m a bit surprised at the recommendation from Flex-o-fold. Seems
like a lot of prop for a boat that is essentially 30 ft with a 15 HP engine.
For perspective, a friend’s J/30 with an 18HP Yanmar has a 12x9
Martec. The Gori for my C&C 38 with a 36 HP Universal @3000 RPM is a 16x10, and
the Martec recommendation was 16x10 ½.
Suggest you contact Flex=o=fold and discuss the recommendation with
them. They may have made a mistake in one of the inputs for the recommendation.
For example, the reduction gear: A prop for a 2:1 reduction gear would have
more pitch than one for a 1.5:1 reduction. IIRC there are more than 1 reduction
gears available on the Yanmar engines.
I would also contact Campbell, MaxProp, and Gori to see what they
recommend.

Subject: Stus-List Prop Size C&C 29-2
I’d like to tap into the collective experience of C&C 29-2 and/or
Yanmar 2GM (15hp @3600) owners.
My 29-2 , acquired 3 years ago, had a 15x9 3 blade fixed prop
installed and 15x10 2 blade Gori spare. This was my first diesel engine and
initially I was quite pleased when I could reach 5knts at about 1800 +/- rpm
and would top out around 2200 rpm. After learning more about diesels I realized
the boat was overpropped. The next season I installed the 15x10 Gori and the
overpropping is worse – black smoke starting around 2100rpm and reduced ability
to push thru wind/waves. The Yanmar tach shows 3600 max rpm in neutral and
also matches the reading on a laser tach at 2000rpm.
I’m looking for a new prop and am considering a Campbell Sailor, 2
blade Flexofold, or 2 blade Max Prop. On the basis of the current performance
and C&C owner’s manual I was thinking that a correctly sized 2 blade prop would
be 14” diameter and 8 or 9” pitch.
I submitted a sizing/quote request to Flexofold and they recommended
a 15x11 – which was not what I was expecting.
I’d be grateful to hear what type/size props other listers have on
their 29-2s or Yanmar 2GM-15s and how satisfied they are.
