Just purchased a 25 fury for my 200 opti. I had a 26 trophy it did a pretty good job. I have tried a 25 and 26 tempest and 25 trophy. Best speed #s came from 26 trophy. Seemed like the tempest wanted to lift the boat to much and the 25 trophy was in the rev limiter way to much. After looking in the owners gallery see lots of p4s run with tempest props and see the rudes running 75+ mph? I have changed my set up several times to get the best performance I can. I have learned this boat is very load sensitive and I have restocked accordingly. I have not measured prop height but my inner plate is about 1/2 higher than outer plate with some torque. Water pressure is say from 12 to 18 and sometimes even in low 20s. Boat has no chine walk. This spring my speeds where really low mid 60s rpms still 5650-5700 then 2 ears came off the prop this could be why my speeds have been going down.. Ok so lets get some feed back I cant believe with all the P4s out there that no one has run a fury, I am running mine this tuesday and will put the #s up then… Sorry for the ramble, Earle Hammod http://www.knuckledownlures.com
