itīs a 3 blade.
We had our local Yanmar dealer calculate the right size based on boat size, weight (the reel weight in the water with mast, sails, fuel Water people e.i) Flex O Fold in Denmark recommended a 3 blade 17x13 or 18x12 (we had the last one when we bought the boat last year) but it dinīt feel like there where any power in and we could get the engine up 3600 rpm. |

Hi Gertjan,
If you are looking for a great deal I can offer you my Variprop which we used to our Hanse 400 during three summers in Sweden. Variprop is a German feathering prop and they claim it is probably the finest featherering prop in the world. Should not be mixed up with the cheaper Variprofile. Variprop is the "high end" prop and quite expensive. However - we will sell it at around half price which should be lower than a new Flex and Fold.
Pls note that you will increase speed under sail with 0.1 knot compared with a folding prop model! Not much but for the racer it is important:-).
What we offer is a three blade with self adjusting pitch and it has EXTREMLY good manoeuvrability in reverse.

Did anyone of you have the 2-blade Flexofold 17 x 14 on H 400 with Yanmar 40hp?
And what rpm did you have on full speed?

I do not have a 400 with 40 hp but a 355 with a Volvo D1-30 (approx 7 tons).
I bought a 2 blade Flex-O-Fold 16X12 following Flex-O-Fold calculations. I can motor at cruising speed (6.2 - 6.5 knots approx) at 2000 - 2100 rpm. This is now 300 rpm lower than with original fixed Volvo propeller. It fits perfect to my yacht so I should be confident in Flex-O-Fold calculations.
Hope this helps a bit. |

Something does not match here. I can make with 18x12-3 only about the nominal 3000 rpm on Hanse 400. How much is your max rpm with 18x14-3 and are you sure these are dimensions of your new prop? On my opinion and experience you may have now ok prop for calm water but it is generally quite heavy. |

Hi Sulutime,
I suppose you mean 17x14 on your H400! What is the maximum rpm you reach with the 17x14? Do you reach 3000 or are you closer to 2800 rpm with the 17x14 which should be the case in theori? BR Morgan
