Do you pronounce electrocute with one yell or two?

Seriously in the US Navy they pronounce a liuetentant as liuetenant but in the Royal Navy we always pronounced liuetenant as 'lefttennant'even though the spelling was the same when written out.

Leeward (i.e down wind) was luward
Gunwhale was gun'l
Coxswain was Cox'n

Woe betide those who could not get their pronunciation correct.
