Don, I made a lever arm tool to assist in installing and removing my A4 from a Ranger 29. With the use of the tool I installed my A4 from the back of a pickup onto the motor mounts in fifteen minutes. That time includes the hook up time. I did have the use of a jib crane at our club. Also, help install A4 in Cal29 using boat lift arm in about the same time. Also used chain hoist on both so that I could control small movements. If anyone is interested I will post measurements of the tool. Pictures can be seen at:
