Yes, about 15-17 inches, low enough that you can slow down
and cool the engine without the horn sounding on every
landing. Depending on the model of your Bonanza, you can
use approach flaps and gear at 152 kts [if my old memory
works] but some models have much lower speeds. You will
need to plan your descents so that the airplane can slow
down to Vlo and Vfe without needing to shock cool the engine
and without hearing the horn.

A normal approach would involve a descent to TPA 2-3 miles
from the airport, then slowing to Vfe, gear down as required
to begin the descent at 700 fpm/85-100 kts depending on
traffic.
If your Bonanza has three green lights, check them 5 seconds
after you put the gear lever down. If yours is an old
model, with just one green light, understand that the gear
down microswitch is on the gear housing under the center
spar cover and it is looking at the position of the gear
housing. Since the Bonanza and Baron use steel push/pull
rods to operate the gear, if one gear leg is up or one is
down, the other two have to be in the same position unless
the steel rods are bent or the housing has broken. Have a
mechanic show you the system while it is on the jacks during
the 100 hr or annual.

On a flight, take a ruler up and set the throttle at the
power you'd use, 15-17 inches and measure the position of
the throttle and then your mechanic can set the warning horn
microswitch in the correct place.
