I do not get any noise or oscillation. With the Yanmar, they recommend that
the transmission is placed in reverse under sail, otherwise you will damage
the transmission.

Thanks for the help! This is a great list!

Do you get a lot of noise or vibration while under sail with a 3-blade prop
dragging through the water?

Ehen I switched Isa Lei #240 to the Yanmar, I used a 13x13 3 blade.  It has
done a wonderful job for the past 5 years.  Plenty of speed under power,
plenty of power to pull some one off a sand bar.

Faerthen,

I have done research on the Yanmar 2GM20F (13HP) and found the optimal prop
is a sail pitch 13X13. This prop handles river currents and a good sea with
winds.
