Over current protection (fuses and breakers) is there to protect the wire.
Check your wiring to ensure the gauge and rating is sufficient to meet
those standards before swapping out the breaker for a larger one. I think
the wiring for the windlass on most early hulls was AWG 4 and 105°C
insulation. You need to check that to be sure. If it is that size and
rating then you probably could go with a larger breaker according to the
rules but I think 135A might be at the hairy edge. If someone ran that
wire bundled with other wires then 135A is insufficient protection
according to the standard.
Make sure you check both the positive AND negative cables as well as ensure
that there isn’t a smaller wire coming off the windlass.
Good luck
