I just bought a 69 Larson 18' boat with a 135 horse Johnson without power tilt. The motor has tilt lock where I can pull it all the way up and it will hold in that almost 90 degree position. It also has a prop where if you pull the motor up about half way you can flip the pop down and set the motor down on it. The prop rod is located in the base of the mount between the lift struts and looks secure but I was told it is not adequate for towing. Is that "kick stand" good enough or should I be getting a transom saver?
