Has anyone put SeaStar on a 400? Wondering what size hoses for best fit, so it's not too tight or to much slack. I also have a 6" JP. I also understand that I need to cut the dash to fit the new helm. People say this is one of the hardest parts. Has anyone just tried a board as backing to run the pilot bit of a hole saw thru? Lastly, I priced a system @ C&O at one time and they said I would need to get a new steering wheel? I assume this is true, but why? Thanks, I have searched many of the forums but haven't found the exact answers I'm looking for I guess. And if anyone has performed this on a 400 any input would be great that would help make this as smooth a process as possible.

Thanks
