The
EMERGENCYsection of your POH should contain information about the use of CSU and retractable (I presume you meant retractable)undercarriage or landing gear, in the event of a glide resulting from a total loss of engine power. The glide speed is usually subject to given conditions, eg; no flap, gear extended, cowl flaps closed, etc.
A coarse prop may reduce drag and RPM loading as stated in the previous post, but procedures should be in accordance with the POH. It would also be prudent to consider the gear failing to extend, in which case the coarse propellor will be less likely to bend on impact, and could cause your nice little aeroplane to flip on landing.
Food for thought. Best bet is to read your POH thouroughly and consider the variables.
