You said the water temp is 77F. What wattage are you using for the basking lamp and what is the temp of the basking area? (To check the temp, put an object the height of your turtle where he usually basks under the light, and put a thermometer on top of it for about 20 minutes. Then check it.) For a healthy turt, the basking area should be 88-90F.
Unless you're using a really high wattage or you're using a 160 watt UVA/UVB combination mercury vapor bulb, a light that's 1.5 feet away from the basking area sounds like it might be too far away to produce meaningful heat. What kind of bulb are you using, and again, what is the wattage? If it's a regular lightbulb/daylight bulb/special basking bulb/etc., does your turtle also have a UVB light to bask under (regular UVB lights are flourescent and don't produce enough heat by themselves)?
