Checking drive train after stuck prop fouled on rope

I accidentally ran over a mooring pendant last week
I tried to free myself by using reverse, then fwd. Unfortunately, it did not free
up and I heard a loud thump. Thereafter, the engine could not turn the prop.
I briefly looked at the shaft and it did not appear to be rotating in fwd or reverse _ in the panic of the moment . After diver removed the rope I
arranged for a tow to be hauled out. During the tow by a small 25hp boat,
I found that I could get some motion from the prop in fwd and reverse.
There was 20 knts plus of wind I did not push the engine for more than a couple knots of speed to assist in moving. I am not sure if any permanent damage was done. I looked at the Indigo prop and it appeared not to have broken sheer pins as it was tight on the shaft I saw some calcifcation between
prop and shaft whic was not broken So I think prop is still on tight and properly.

The prop is a Indigo ss version and the 1 inch shaft is bronze

I wiggled the shaft in the cutlass and noticed 1/8 inch up/down sideways
play. The cutlass has been approaching replacement time for a few years
so now is the time.

My main concern is how to check if transmission
has any issues in fwd or reverse?

On the hard with the shift lever put in fwd I hand rotated it freely for
180 degrees, then the fwd engaged and it was now turning the
crank in either direction when hand rotating the shaft. Is it normal for the
tranny to take part of a rotation in fwd to engage?
More importantly, How can I cjheck for damage to gears or disks iin
fwd and reverse?

Comments Appreciated

Best Art
