To the original post... I think a pin is a good idea for the motor mount and the mast crutch. I remember someone posting quite some time ago that the mast crutch came loose while they were trailering their boat. It seems like cheap insurance. I attached some annotated pictures of the pin that came with my boat.
To the comments on the Torqeedo etc..... I have been using Torqeedo motors for almost 10 years. They are fantastic for my use. It is particularly suited to motoring the boat in tight conditions. It allows slowing down to a crawl without stalling out. It reverses without the side kick from spinning the motor, and can break either hard or very softly.
I started with the 2hp travel version with the black battery. I found that the motor mount flexed under load. I do not think they sell that version any more. When they came out with the 1003, I upgraded to it. It has great power, control, and a longer range that its predecessor. I have used it for 5 seasons now. I love it.
It does have a lock down so that it will not kick up when used in reverse.
I had some difficulty with it shutting down when I switched from forward to reverse quickly. You need a short hesitation at the stop position. When I mentioned this to Torqeedo, they already had a software update that programs a very slight pause even if you do not pause it yourself.
I typically leave the motor on the motor mount while day sailing. I added a piece under the tiller which catches on my motor mount. It holds the motor in the lifted position with the battery up and keeps the motor from flopping around.
This year I got the larger battery. The upgrade to the 1003 from the first model was a huge improvement when used with the U20. The larger 915wh batter (which comes with the 1003c) has about 70% more power. I used to have sufficient range with the 530wh battery. Now, at least for my usage, I have plenty to spare. I still check the battery level, but no longer worry about it, even when the wind picks up and I know that I will need more power to get home.
If you can live with the range and price, it is a great choice!
