Just bought my first mudrig. 06 gator tail 18 x 48 center console with a 06 35 gtr. Motor seems to run fine once it gets on plane but is slow as hell from the start. I measured the prop and it was 11 and 3/4. Didnt have a gps with me but with me 185, buddy 220, and dog 50 it was moving on pretty good but just slow coming out of the hole. Would get 4000 rpm WOT heading up current playing with the trim. Will a new prop help with speed getting up on step. I'm a newbie, so any suggestions would be appreciated. thanks

Most props will lose alot of their performance as the cup wears off the ends. Some of the GT crew can tell you the original dimensions of the prop, also a pic will help.

You can use your existing prop for a spare.
