I have had this boat for about 5 years now and it is my first boat. It is a 98'. When I first bought this boat it was running high 60's/ low 70. I have since banged my props up and had them redone a few times and ever since I have continuously lost speed. I had my prop guy do the proper cupping on the rear prop and got back up to 64. When I got home I looked in the back of my car and noticed that I forgot to install the 3/4 inch spacer that goes between the two props. I am hoping that this caused my lack of speed.

My question is does anyone else have this rig with the Yammy TRp and if so what kind of speeds are you running?
