This is interesting I have a 2015 18 TRX with the 200 pro XS 2 stroke and with a 24 fury I couldn't get it above 65 and only turn 5700 rpm I have an Atlas Hydraulic Jackplate to play with engine height I put a 24 Tempest plus on and finally got it to 68 at 6000 rpm by myself with 1/2 a tank of gas and all of my tournament gear just put a 25 Tempest plus on to see what it will do should easily be running close to 70. Probably going to have to send this 25 Tempest to Mark Croxton and have him work his magic on it
