Hi Rich. Thank you for your service to our country. I would call my dealer if I were you to get some ideas from them on this, but I did a quick search on the site for threads that were related to this problem. Hope this helps:
210 hydrolic steering
If you use the Search link above, enter "steering" or "hydraulic" then click on Show Post and submit the search, you'll see several pages of posts with those words in them. But with Show Post instead of Show Thread you'll see a short section of the text and be able to search them all quicker. To do combined word searches enter "hydraulic steering" for just those words. If you enter both words without the Quotes it will bring up every post that has either word. But with the Quotes it will only show posts that contain the phrase "Hydraulic Steering".
Also I add hydraulic fluid on my 215 via a inlet that my dealer placed behind the steering wheel on the console. You unscrew the black cap to add the fluid. Your motor was probably rigged by your dealer so you may need to contact them to find out where yours is unless it is in the same place as mine.
