You are going through the same processes I went through when I carried an auxiliary, I used to lock mine in place and tie a rope around it just in case. I also found out you can only lay the motor on one side for fear of oil escaping into the carburettor and then being a non starter. Steering was an issue with a 640 quicksilver, but once it did bring me closer to shore to drop an Anchor, then get a tow in. Then there's the servicing costs, so I decided to invest servicing Money into Sea Start, albeit that is a little restrictive on distance from shore. But it saved the weight, released the space and all the hassle that went with it.
