Hey everybody..new here and am hoping I can get some advice..I have a 2014 Ranger Reata with a 150 Mercury 4 stroke..I have a 4 blade 17 pitch prop (factory) on it right now..the problem is that I am seeing speeds only in the low 40's..I was hoping that it would at least see 50..anybody have any suggestions as to what I might do? I am using this for fishing tournaments as well as lake fun with my family..but the speed thing is driving me a little crazy...
