A few boats are constructed with an inspection hatch for the propeller (but
a sizeable tube will take up space in the lazarette).
There are several types of shaft mounted rope cutters available.
(Full disclosure: I run a small side business where I promote one type of
those shaft mounted knives.)

Subject: [PUP] Ice Dancer 10/30/05: Excitement at sea
Email relayed from Ice Dancer en route from Hawaii to California:
At 7:30 last night, I was napping and Gail was at the helm when all of a
sudden the main engine stopped its usual purr and pilot-hourse alarms
started blaring. With flashlight in hand, the problem was confirmed: a
drifting fish net had wrapped into our propeller and choked the engine. I
tried cutting it loose by the light of a flashlight in one hand and a knife
in the other, while holding my breath. It soon became apparent that we
should wait for morning. We drifted through the night and early this
morning pulled out the scuba gear. By 6:30 we were cut loose and,
thankfully, there was no apparent damage to the engine, transmission or
drive shaft. We were off, again.
At 7 a.m., we are at 29 04N 139 08W, steering 68 degrees true at 7.5 knots.
While suiting up with the diving gear, we noticed a little shearwater had
landed in the cockpit for a little rest. Maybe it was our good-luck charm.
Lots of excitement.

A sheetrock knife kept very sharp with a little lanyard attached is very
useful to cut things away from a prop shaft. If you're not familiar with one
of these, it's a little knife with a sharp curve or "hook" at the end. You
can get the tip under whatever you're cutting away and have tremendous
leverage to cut with, using the back of that curved blade.

If you tell the truth, you don't have to remember anything.

Looks like a good solution, though it may lack leverage.
