312 fastechs are not a wise buy?

I have never been in one myself there were a couple guys around here that one both of them said that at cruise they were great but when trying to trim out for speed the boat tended to rock on the step. Almost like a constant porpoise that the boat would not power out of. Again I never rode in one or drove one.

A 312 was my first "go-fast"....and we then moved into a 382
. The 312 was too close in price/size to the 353 IMO and the twin step 353 was nearly as fast with the same power. I don't recall a porpoise problem but it's been 10 years. Mine had 502's and ran low-mid 70's. Typical heavy/slow Formula but the quality was good and it served us well. We overnighted often and upgraded for the space.

I have a high horsepower 312. At times it tends to chine walk when wound out, but I'm probably well beyond the power that formula ever designed this boat for. I think mine rides fine and was a big upgrade over my 271. I went 312 because a 353 was out of my price range and a 292 wasn't really much of an upgrade over what I had.

where are people saying this? 312 is definitely a heavier boat, I know a few who owned and loved, they just went bigger, I think like said above most are underpowered with 454/310 mpi's you most definitely want 454/385 or bigger
