i hove two ways to do this,,<br /><br />1. stor it in the cabin and when main breaks mount to transom, which is light80 pounds and easy to do from boat...no worry about it being stolen, no worry about it falling off, wont have to stay in the "up" position all the time.<br /><br />2. mount it on the transom that way i can test run it every now and then, will be able to use it for slow speed cruising, conviently there wont have to mount if needed.<br /><br />so should i mount to transom and leave it in up<br />position or STOR it in the cabin ?, which i have plenty of room in the 21 footer.
