@Mike Lopez Welcome to BBB!
I used to own a Tracker Pro Team 18. But mine had a 90 HP Merc.
If your boat is setup similar to mine, there will be an oil tank that you fill with 2 cycle outboard oil and the engine will take care of the mixing of fuel and oil. Some boats will have this tank on the outboard itself. Others will have a tank in the boat, usually in the rear bilge area. If not, most outboards run on a 100:1 mixture.
For gas, use regular grade. If you can buy gas at the pump with no ethanol, do it by all means. Otherwise, use gas only with 10% ethanol or less to avoid major engine and fuel system problems.
Regarding the kind of oil, by good brand name tow cycle outboard oil. Merc offers their own brand. Yamaha oil is also very good. Avoid the generic brands sold at Walmart and other major retail outlets. They save you money in the short run but will cost you more in headaches
When I had my Merc, I used to run LubriMatic Two Cycle oil that I bought from Walmart by the gallon. I ran it for several years, and then decided to try a different brand name oil. When I made the switch, the smoke from my motor declined by about 75%. I had wondered for years why my outboard smoked so badly. I just thought it was a Merc trait. But it turned out to be the oil I was running.
You can get Two Cycle oil from Tackle Warehouse here:

I bought my boat brand new in 1994 and it came with little or no documentation.
Starting it is pretty basic, but varies somewhat from motor to motor. If I remember right, mine was pretty much just hold the primer button while turning the key. When it fired, let off on the primer button. But that was more than 10 years ago, so I might be confusing my current boat with my old boat.
Always make sure the primer bulb at the transom is squeezed up enough to make it hard before attempting to start the outboard too.Winterizing involves using fogging oil to coat the engines internals, to prevent corrosion. You'll also want to make sure the fuel is stabilized and that the batteries are kept charged over the winter months.
If all else fails and you need to find info, try visiting the Tracker Boats website and finding their contact info and give them a call or use their website's live chat feature to ask someone your questions.
There is a list of boat manufacturers and contact info here:
