Well it worked like a charm. I used a 1/2" mooring shackle on the stbd side loop after unplugging some wires and a vacuum hose to get clearance. To that I ran a 3/8" dyneema line with spliced loops in the ends. Ran the line over the lift hook, through the port side loop and then put the loop end on the lift hook (boat club hoist (4 tons)).
Took the load off the bolts with the hoist, undid the nuts and swung the engine away a little.
Got my steering cable changed and lifted the engine one bolt hole to try and get the cav plat in the right place. Never disturbed the lower bolts.....
No drama, just like I like it.
The lift line now goes on to be used as a single point lift for my Rhodes 18 sailboat.
Thanks for inspiring confidence.
