Re: Sea Ray
I would first check the gas tank to be sure that good fuel is in it, no water in the bottom, no separation of gas and alcohol, etc. Change all fluids and filters, lube all grease fittings, you will need the maintenance manual for this to locate what needs lube and what type lube. After 5 years I would change the water pump impellar also. There is probably more but that is what comes to mind right now. Hope this helps.
