RFM! After motoring out and getting the sails set, idle the engine for a few minutes to cool down your diesel and trim sails, then when you are ready, shut her down. Then shift the transmission into reverse. Last, check the coupling for alignment as Edd described. This will lock the prop from spinning and the blades will close for sailing. FWIW, It should all be in your manual.

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.

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. Rick Brass From: CnC-List [ mailto:cnc-list-boun...@cnc-list.com ] On Behalf Of Martin Kane Sent: Wednesday, January 15, 2014 10:01 AM To: cnc-list@cnc-list.com 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.
