Hasn't Darris/Allison already tested,and is selling/stocking the Uflex/Mercury steering cylinder ? I have read all those uflex/seastar threads,I just have never myself,experienced the issues ppl. claim with the 5345 cyl. Guess I am lucky,or maybe because I have the seastar bleeding machine ,and keep mine tight and bled out. but the 5345 works fine on my xb2003,and 2 other faster boats,which i have. I just dont buy the hype,for needing anything beefier,unless you constantly run on the wire,(which a 225pmax isn't gonna' be doing),then string steer is for you. But ,if you can afford the HD version,then I would always say,bigger is better,GL and play safe,,love them Ally's
