i've run a '77 18' for a couple of years now. it has older omc 120 and does very well on fuel as well as power. i'm nearly finished with my '75...hope to be in the water in acouple of weeks. i'll let you know how it works with a hermco bracket and 150 2 stroke yamaha.
i grew up fishing on a '69 20 sf with a 200 rude. now my dad has another '70 20 sf i/o. while the 18's lack the space on the forward deck, i prefer the liner design of the 18'. i must admitt, however, with both an 18' and a 20' side by side in the shop...the 20'does have the better lines
