Hello everybody,

does anyone have experience with the Gori 16.5 x 11 folding propeller on a 345er with the Yanmar 3ym20 or Volvo D20. I would be interested in the speeds at different speeds - eg. at 2000, 2800, and at full load as well as the max speed of the engine.
I suspect that the propeller does not fully unfold on my boat.

Many Thanksc
Greeting
Joachim

I also have a Gori 2 blade folding prop.  Not sure what size it is.  It is fitted to my H385 with a Volvo D1-30F engine and 130S saildrive.

On commissioning the engine was tested for speed against revs.  Subsequently I found that the log was over-reading so I adjusted the figures accordingly.

RPM kts
1500 4.7
1750 5.3
2000 6.0
2250 6.5
2500 7.2
2750 7.6
2900 7.8
