Have decided to go with a new Barracuda. The only query I have is the dealer assures me a 50 Etech is enough power for this boat, I wanted to go with the 60 but he tells me they are the same cubic output only the 60 has a variable exhaust which gives it slight more kick after 1200 revs, simialar to a power band on a motobike? I would like to hear from anyone who might be able to shed a non dealer spin on this story. Ta.
