[QUOTE="Quackrstackr, post: 146417, member: 437"] Hard to say without an rpm reading but I took a wag on your setup on a prop wizard and came out with props from 10 3/4 x 12 up to 10 1/8 x 15. You will drop 200 rpm for every inch of pitch on a prop and you want to run in the recommended rpm range for your motor (I think up to 5500 on yours) without lugging it. Hard to say about different prop brands/models too without just trying them. They all have slightly different blade geometry and will all run a little differently. [/QUOTE]
