I have never been able to get my Z8 dialed in for my speed. I am looking for advice on what direction to go or what to try next. My setup is a 2010 Z8 with a 200 Pro XS. I have a 10" Bobs Hydraulic Jack plate and a tempest plus 25 prop with 1 plug removed and the other two are the hollow plugs. I have dual power poles and 4 batteries in the rear. I have read and searched quite a bit and my boat doesn't react like I expect it to based on what I have read should happen. Currently, tournament load I can maybe hit 63.5 mph at 5200 rpms (based on the tach in the dash.) Prior to me installing the poles I would get about 64.5 mph but most of the time would come back to almost 63 mph cause It would start chine walking pretty good around 64 to 65 mph. As far as my pad to prop height. When my jackplate is all the way down is when my boat is fastest. It has always done this, before my poles, and even when I ran a 25p fury. I can get my boat going as fast as it can with my jack plate all the way down (approximately 5” prop to pad,) as I start raising my jack plate slowly I can watch my speed drop. I’m not losing water psi. This just contradicts everything I have read about prop to pad adjustment. Its not that I am all about speed (I do like it.) Its more of the fact that I want my boat (that I paid all this money for) to be running and setup as good as I can get it. It bugs me knowing I can’t figure it out. I tried running a 24p fury at one point in time and I can’t remember what my rpms did. I do remember I lost about 3mph when I went to it from the 25p fury. Appreciate any help/advice.
