    below are pics of the "jack-bars" that i made for my short transom/longshaft motor boat. a freind works for a machine building company and "acquired" a peice of extruded aluminum for my project. according to my freind who is an engineer, this stuff is extemely strong and laughed at me when i asked if maybe the motor would snap it off. i have taken the boat out twice now and tried to break it off to no avail (with motor chained to transom just in case). my boat goes twice the speed it previously did! i cut the bar up into 2pcs so that the motor would be raised 5 inches from where it sets now. the pics are pretty self explanatory. the extruded aluminum also has t-slots in it where i also bolted the feet to with a bolt and the "t-nuts".

    That looks great! Dink, It would take a dozer to bend that stuff! Now, where do the rest of us get that kind of material? lol

    I've seen that extruded aluminum in McMaster Carr catalog and Grainger catalog. Both are industrial supply companies.

    Dink,

    Nice setup! I agree with everyone else that it would be difficult to break those pieces. The great thing about your design is it also sets the motor back a few inches from transom. An outboard will perform better when the prop is turning in the less turbulent water away from the transom.

    Well done,
    Tom

    not sure how well that size of extruded aluminum would hold up to bigger motors, but they make the stuff much larger. i might have my freind look into how much actual stress and torque its rated for. i had to shave a little off of the bottom of the bars (at an angle) because of the "spray" it created when at full throttle. did look cool though, like a huge pecock tail behind the boat. thanks for the compliment larry, its caused by hanging around poor rednecks too long, you oughta see my truck:D
