I use my boat so often I just drain every thing every time I come in when it's cold, including the drain plug from the boat, only takes a couple minutes, but if you are gonna put it up for the winter, then you should do it this way ...
Drain the block by removing the little plugs in the middle of the block down by the oil pan, push a small screw driver up in the holes just to be sure they are not clogged by rust, sand or debrie, pull the bottom hose off the exhaust manifolds and that will drain them, remove the intake hose from the power steering cooler, remove the lower water pump hose that will drain it and the water pump. Now that everything is hooked back up, Remove the two hoses that go into the top exhaust mainfolds from the manifolds, then hold or tie them up so they are higher than the ports you disconnected them from so you can pour antifreeze into them with a funnel. get yourself about two gallons of RV Antifreeze if you are an enviromentalist, green automotive antifreeze if you're not, I like the green stuff, but mix the automotive stuff up 50/50 with water and pour it into the hoses you tied up until you see it come out the ports on the top of the manifolds, or, depending on how low the nose of the boat is setting, it may run out the exhaust ports and through the "Y" Pipe, sending it onto the ground behind the boat, at any rate, which ever one give's it up first, you know the motor is full of antifreeze, then hook up the two hoses and the motor is ready for spring.
About the drive ... After the boat has been setting over nite, I will remove the drain plug fron the lower gearcase, I'll just let enough gear oil out to see if there is any water in it, water is heavier than oil so it will settle to the bottom over nite, if the oil looks milky, or any color besides green or darker, then I'd just drain it all out and refill it with Quicksilver high performance gear lube Only, do that during the winterization, don't put that off till later and you won't have to worry about forgetting it. Last thing, lower the outdrive all the way to the ground so the water will run out of the exhaust chamber around the prop, after it all drains out, then you can put it back up into a tow position and scrinkwrap the prop and exhaust opening so rain water won't run back into it, you're done. I would leave the outdrive trimmed down all the way I quess just to be sure water don't get back in there and freeze break the exhaust housing.
I have a cover I got from the prop shop that covers up the end of the prop that looks kinda cool, and keeps the water out also. If you are gonna store it for the winter I'd take that Enertia prop off, it is less likely to get stolen, that baby list's for $470 and the lower unit is easier to scrink wrap also.

what would be a good winterization procedure for the scimitar? would putting a good amount of antifreeze in the system and circulating it through help? what about everything else, should the prop come off,?
