How fast is your 33ft and with what power?
 

I have a 1987 33ft with motor's that were built buy the owner before me, I would guess them to be about 400 to 450 hp? We ran the boat last night with two guy's full of gas and the best we could get on GPS was 67mph at about 4900rpm? Is this about right? I thought it should run a little better than that. What did the 33's run new with 420's or the 365's?

BTW, my boat has TRS drives.
