I am not a marine engineer, but I would think 400 pounds would be the min. for floatation. These boats have a funny way of squating down in following seas. I think I remember seeing some specs on the Hermco twin brack that it had 400 pounds of floatation on the twin bracket.

Almost all the engines your looking at are south of 400 pounds, 2 will be over 800 pounds. Personally, other than the gas consumption, I like the merc 250 efi, weighing in at 472 pounds. About 50 pounds more than most of the 150s.

I put a post up on trying to find the "optimal" bracket height for the armstrong I am putting on. There seems to be a lot of discussion, but not much real world experience.
