not too sure on the 92, but heres what my manual says for the 97 with an auto and 350:
2wd Axle Ratio Max trailer
3.08 5000 lbs
3.42 6000
3.73 7000
4wd
3.42 5500
3.73 6500

So really whichever combo you have a 3000 lbs boat should be no probem at all. Personally I tow in 3rd in the city and 4th on the highway, although my manual states I can use 4th under all circumstances. I would however invest in a tranny cooler if you're towing frequently, hell they're less than $100 , to me it just seems like cheap insurance. As for brakes I've towed somewhere around 4000 lbs with the stock brakes, but I would defiinitly recommend trailer brakes for a boat, they may even be required by law where you live, again a brake controller runs at less than $200 installed, best bet is to visit a local trailer shop for that one though.
