I have an 07 PII w/ 07 Merc Opti. I have ran a 2 differenct 25 Tempests, 25, 26, and 27 Trophy. 25 Tempests and the 25 and 26 Trohpies all got into the rev limiter on top end. The 27 Trophy I could only turn about 5600 rpms in warm weather. I am now running a 27 Tempest and it comes out of the hole great and runs super on top end. I can get it into the limiter under perfect condtitions in the cool weather, but I think this prop will be perfect in the warmer months. On the holeshot, make sure you do not start trimming at all until the boat is out of the hole. Do not be on the trim as soon as you get on the throttle. If you are already doing this correctly then the PVS holes need to be adjusted. If you have any more questions or need more detailed input on this just get on here al let us know. Be glad to help!
