Boat's propellers from San Remo (7)
I believe the answer is:
oarsmen
'boat's propellers' is the definition.
'oarsmen' can be an answer for 'propellers' (I've seen this before). I am not certain of the 'boat's' bit.
'from san remo' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'san'+'remo'='sanremo'
'sanremo' is an anagram of 'OARSMEN'.
Can you help me to learn more?
(Other definitions for oarsmen that I've seen before include "possibly eight in a row" , "They propel boats manually" , "Male rowers" , "Male propellers of boats" , "Scullers" .)
