Recomedations for a propeller for Swan 38

Hi,

it is time to replace our old 17x11 Volvo foldable three blade propeller. As engine we have Yanmar 3ym30 and the gear ratio is 2.62:1

As many probaply know reversing with a Swan 38 is a bit difficult in thight spots due to quite strong pull to the side.

Does anyone have a idea which type and size of propel would work best?

Thank you in advance,

Sebastian Eskelin

Dear Sebastian,

you can find many threads on this matter, but I think the most useful one for you is this, which speaks of a sister boat and same engine (which by the way was my previous S&S Swan Only You): https://www.classicswan.org/forum/post_thread.php?thread=2308

The prop I opted for was a bit smaller then the original 17" but with much more clearance the vibration/noise reduction was incredibly satisfactory, and with a higher pitch I could motor well above 6.5 kn .

I hope this could help!

Fair winds!

Sebastian, 

17 years ago we installed Flexofold 16 x 14 RH 3, following Professors calculations and suggestion. Our engine is Bukh DV 24 ME. We are very happy with the propeller. 

Best regards
