As far as winter storage, unless you plan to Completely!!! drain the fuel so nothing is present, which is hard to do, this is a bad idea, the less fuel the more water will form due to the air in the tank, your best bet is fill her about 7/8 or so, you want some room for expansion, and add star tron fuel enzyme treatment to prevent the fuel from breaking down, the treatment will allow fuel to pass through if some water does break down and not damage the engine, also add a good fuel stablizer, this will give the boat a slight boost of octane and keep the fuel conditioned and safe for next season. I've done it this way for about 20 years and never had a single issue come spring, guys who leave them empty of half full tend to have more issues from what I've seen. Also, fog the engine with fogging oil, remove each plug and spray can directly into cylinder, crank over the engine after each spray just enough to coat the cylinder wall, after all are done, run engine until she bogs down and stops running and your now winterized. Change lower unit oil and filters on the engine in the fall, that way if you see water in the lower unit you have all winter to rebuild or fix it, waiting to the spring like many do can cause you lost time on the water if you find it then as everyone is taking their boats in for service and the waiting lists get long. In the spring, start her up with ear muffs in the driveway and run her a while to get the fogging oil out, and then run her on the water, open her up good the first trip and your set for a great season!! Also, remove the clear plastic curatins off the boat, if you leave them on they will get a foggy film that will not come out ever, and will drastically reduce the amount of time you get out of them before they need to be replaced. Roll them, do not ever fold them, putting wax paper on one side and rolling that direction so the plastic never touches is best, you should clean the plastic with a marine plastic cleaner, anything else will destroy the protective film and reduce itsl life, and salt is just as bad on them. There are various protectants that work very well to both clean and polish the clear plastic so it will last a long time.
The levers under the chains should push up and allow the chair to slide forward and back, the white knobs under the chairs screw loose to allow you to raise and lower the pedastal itself for better chair height if perfered, tighten it down and she will stay there.
you should be able to access owners manuals off the Grady website for the boat, or cusrtomer service can assists you if you call, but the manual should be online for ya.
Best of luck with the boat!!
