I'm sure you must be talking about the 16C from Mr vincent @ SCM.
I can assure you that he has a boat very well built indeed. I think he's an old chum of Mr Rings, but isnt too backward in giving his opinion on what improvements he felt were 'a must' for that boat. I.e stringer/ floor arrangments. I think the flors now stepped, more like a phantom and the knees come up bellow the back seats.
Mike will assure you that you can stick a 60 degree 175 ficht on it no prob. I can vouch for having seen one go like stink with a 135 Merc 2.0L. Which are decidedly lighter.
have decent pics @ home, will post if u want.
Anyway, how comes you got some built, i tried for a year to get a price
i think theres some conspiracy here
