I wouldn't be afraid of something with Detroits either as long as they're the 71 series. A set of C18 cats in a 54' Bertram SF, the boat would fly. I ran one with 12v71's TI's (hardtop) with 4600 hours without rebuilding them and the boat ran 30 knots at 1950 rpms........Cat's would probably cruise the same boat around 36 knots.......maybe more.
As for the Cabo's and Vikings not having CAT's they both heavily installed the pre-common rail MAN's from 98-2002. MAN was offering great incentives to manufacturers, the HP to weight ratio was higher then the CAT's then and fuel consumption a little less and a little more speed. But, you'll still see some CAT boats if you look......That was until they started seeing a LOT of problems with the MANs, also a lot of complaints about the rough running at trolling speeds, maintenance costing 3x the CAT's, black soot, and fumes. There was then a MASS exodus towards CAT's when the C series came out and you'll see most all of the Vikings and Cabo's from 2002-2005 have primarily CAT's.......until the common rail Man's came out and that's sort of leveled the playing field......... |
Looking at 54 Bertram with Cat 3412. would like your input regarding that engine. It appears a lot of Bertrams were repowered with this option. Also, any idea of fuel burn with this power? I realize the difference may be minimal, but what do you think of these vs. a C series motor? Thanks in advance.
