Re: euros 39 nprop size

Your question could have a very long answer...prop sizing is not an exact science.. You need to know your gearbox ratio and check the shaft diameter and taper are correct. Also know your max RPM and HP of your engine. Use the waterline length, beam and displacement and google "prop size calculator". It sounds like the prop may be suitable but these calculations will help you.
