My Yamaha F150 owners manual indicates the tilt support lever should not be used when trailering the boat since it could slip out of place. <br /><br />I know of the transom savers that many folks use but I have a few additional problems to make this work for my rigs setup. First it appears that the transom savers only mount to a roller at the rear of the trailer and my trailer only has bunks. Second, there are lights on ther rear cross brace where I may otherwise be able to mount a transom saver. Finally, the distance between the trailer cross brace and the lower unit is considerable further than available with most transom savers.<br /><br />I know Merc sells something for their outboards that holds the lower unit up but I can't seem to locate anything for my Yamaha.<br /><br />Helpful advice appreciated<br /><br />Kevin
