Ericson 27 Sidney
Considering installing a feathering propeller on my Ericson 27 with a Westerbeke M4-30 25 Hp, currently I have a 3 blade 12" 10 deg, Kiwi is suggesting a 14" 21 deg! Any thoughts out there?

thanks

Your prop business owner will know what you need based upon their prop specs.

If your going with the Kiwi prop, then Id follow the manufacturer’s recommendation.

I would check your boat that you have the room between the hull and the prop shaft for a 14” prop. I would be sure to tell the prop people the measurements from the shaft to the hull, the transmission specs, and the motor specs. From that they should be able to help you.

Just go with manufacturer recommendation first. You can easily adjust the pitch angle after trying out.
My adjustment guide is to be able to run my 2GM20F engine at 3400 rpm and a little more if possible.
