what difference will an inch make
Just had to fit a new prop to my Mariner efi 60hp on my 4.8M Ribcraft, i am pretty sure the prop that was on the engine was the original one.
It was marked 10 38 13P, so i assume its a 10 inch diameter and a 13 pitch.
The Solas prop finder recommended the Amita 3 which is 11.1 inch diameter and 13 pitch.
Mercury prop finder shows a variety of prop sizes 13 pitch but diameters of 10.3- 10.5 inch.
Will i notice much difference with the solas prop. Haven't had chance to test yet as its windy as hell here in SE Ireland,
