Great job guy's !!!
A couple of things to add here , don't forget about your trailer , and don't forget about your batteries and electronics . when speaking of cranking the engine to remove access water from the impeller , I would suggest that the kill switch be used in the beginning , I would not risk the engine starting at all out of the water , 5 seconds is all it would take to kill an impeller , not only that but if someone gets close to the prop without you seeing them or a pet , it could be dangerous .
Service your trailer , double check your lights and make sure you dont have any standing water in the lenses , tubed trailers will have pockets that water can stand in , beam trailers can build up ice from a wet ride home , the bunks themselves will freeze which makes it easy for the boat to slide and move around if the boat is not fastened properly , double check your straps and ratchets , make sure that when you get it home that the trailer angle is stored high in the nose to allow any access water to exit the rear of the trailer and allow water to excape the hull , always make sure your hubs have a shot of grease to push any access moisture away from the bearings .
Batteries can and will freeze , the best thing is to remove them and store them in a warm enviroment , and charge them as soon as you get them home , charge before removal or charge in the house if you have a battery tender , either way it is a good idea to purchace a battery tender to keep life strong in the batteries .
Your electronics need to come in as well , make sure your connector ends get a little dielectric grease to help fight corrosion , both the battery connections and sonar connections .
All outboard engines need to be winterized , if it is not going to be run for a while I would also suggest fogging the cylinders , as well as following the above post's , remove the spark plugs , slightly fog the cylinders , rotate the crank via pull cord or starter , then liberally fog the cylinders once more , there is good info on the web about how to do this , this is the method that I use .
