Might as well chime in .My 1982 34' c/b with a 3GMF20 ,martec folding cruises the same as Legacy III about 5.5 to 6 max around 3100rpm.When I first got the boat and brought it up to NJ from Annapolis she had a 2 blade sailor and cruised to 7knots pretty easily.JimGalaxyBrielle, NJ Date: Tue, 14 Jul 2015 08:16:03 -0400 To: cnc-list@cnc-list.com Subject: Re: Stus-List Best Engine?

Hi Brian, After seeing Legacy's speed with a 3GM, I feel less bad about our speed.I've got a 1978 34 with a 2QM20 and get right around 5.5 with a Mar-Tec folding prop, too.I though she was under-powered, but I guess not. I try not to run wide-open, so I can only guess we'd get to 6kts.Good news she sips diesel fuel. Chuck BC&C 34 ElusiveSomerset, MA
