Winterizing and Haul-Out: Prop shft coulping on M-25XP

[down_shift]

Getting prepared to winterize my C36 MK1 tomorrow by reading the owner's manuals, threads, and Maine Sail's tips (btw - Walmart does carry the marine/RV propylene glycol based antifreeze in a Prestone clear jug).
The owner's manual for the M-25XP mentions nothing about opening up the prop shaft coupling. However, the newer Universal owner's manuals (X-25XPB, etc.) mentions opening the shaft coupling to remove the strain from the shaft while being hauled or on the hard.
Is this good practice on the older boats as well?

Never heard of that, 16 years with our boat, similar to yours. Do you have a link to that manual? Sounds strange. Just never run your engine when out of the water, the cutlass bearing needs water for lube.
