If that is the case we should bring Jerry's machine up here in October.
It should hit 85+ when the water and air are around 40 degrees.

it might have been a spike but the run before it i hit 76.7 and i was porposing a little and we hit 75 all day long the air temp was about 75 and the water temp about the same humidity was 30-40% if that im not really sure it was really low. it was in the evening when the water was like glass hard to find aroung here with all the boat traffic. i was surprised that we hit 79 myself i didnt know that the gps could be off. we were hitting 8050-8100 rpm all day. i weigh 160 lbs too. i think the 158 thermo is a big help no heat fade at all.

I don't know if this is normal but i've raced a gtx sc before with my rxp and I have no problems catching up when behind but when I get ahead I feel like I'm only gaining a foot per second. Maybe I was blessed with a bad performing stock machine because the gtx sc goes a solid 62. I don't have gps but I thought my rxp would be in the high 68s because I only weigh 150lbs. Does anybody else notice they don't pull away a lot from the competition when you have around 5mph on them?

A 5 mph difference in speed isn't going to leave anyone in the dust unless you are racing for a long distance. A person walking at a quick pace is doing about 4 mph. The 5 mph speed difference would be enough to make an undisputed winner out of the faster boat.
