cabin size?

rough water handling?

I am on my fourth Formula, I wouldn't own anything else. Qualiy, service, ride and resale. The only thing Fountain has on a Formula, it may be a little faster. Look at how many Fountains are for sale, and look at how many Formulas are for sale, and compare what there resale is, and there is your answer. One thing to consider, is that in the early 2000's, Formula raised the weight on the 353 about 1000-1200 #'s. My 99' runs 75-76 mph, with stock 502's , and no labbed props, this is with 1000# of cargo and 1/4 tank of fuel, but I mine does not have any options, macerator, etc.,.
