I purchased a 1991 supra conbrio back this spring. The boat is in great condition with only 300 hours on the boat. I have had a few other boats but they have always been outboards or else an external out drive. I have never really worked with an actual inboard motor. The engine is the original 351. I put an aerial tower on the boat this summer also. I got a great deal on the boat and have been very happy with it so far. But I need some help on how to winterized it? I'm new to this boat so the more explanation the better. any help would be great. A check list of things to check would be great also. Also any ideas on what oil to use, any adjustments, and what improvements I might need to make. The only issue I have had so far is the boat still has the points ignition and the gas tank is fairly small. It barely lasts me a day out on the water. Any help would be greatly appreciated. Thanks
