I will be loosening it come spring when I do a haul - but does putting it in reverse adversely affect the engine?
I doubt it has anything to do with too tight, as only the hub is held by the prop shaft nut. If there are too many threads exposed beyond the nut it will bind with the cone though (3.B.2 manual).
Most likely though it is behaving as expected and following the use instructions in the manual will solve your problems.
From the manual found at:
USE The Max-prop works automatically. By putting the engine
in gear the blades will engage in either forward or reverse. The best way to
feather the propeller
• Power at 2 to 3 knots in forward.
• Kill the engine while still engaged in forward.
• When the engine has stopped, if the shaft is still spinning engage the
in reverse to stop the freewheeling.
You can check to see if the propeller is feathered or not by taking the engine
out of gear. If the propeller is not feathered the shaft will freewheel like with a
fixed blade propeller.
In that case start the engine again and repeat the three steps. If your
propeller has been greased properly it will feather in a fraction of a second as
soon as you stop the shaft from freewheeling. Once the prop is feathered,
you can either leave the transmission
in gear or out of gear, it does not
matter. DO NOT kill the engine while in reverse. In this case the blades will
be in the reverse position and will not feather. You can actually use this
feature to drive a shaft alternator
