Currently Im running a 27p Tempest on 2006 Puma with 225 Pro XS. The 27p will spin to 5570 RPM so the 26p should be right in the 5750 to 5800 range. It came new with a 26p Trophy. I like the hole-shot of the Tempest over the Trophy. Also the Tempest seems to get the stern up better. Thought the Trophy is a better handling prop in rough conditions.
