The last time I went to the Unlimited Hydroplane races at Mission Bay San Diego there was an Unlimited powered by 8 2 stroke outboard power units, I forget which manufacture. The boat was altogether different from the usual Unlimited, more of a 38' long catamaran with all those power units mounted in lines of 4 and driving a single prop. Wish I could remember it's name, was owned and sponsored by a big truck freight outfit from LA. Wild to look at and whata sound :eek::D:steering:
