That's just silly. Your not going to hurt the trim cylinders with that little of weight.
The possiblity does exist that your trim system leaks down and let your motor come in contact with the road. A simple solution for this is to cut a short piece of 2 x 4 and hold it in position with the trim. The other is use something like the "wedge" . google m-ywedge or details
If you have a Mickey Mouse transom then all bets are off.![]()
stick a piece of axe handle tween it and mount and lower engine till the pressure is off the trim pistons; this seems like the very best deal all around.![]()
