I have a 42 fountain 2006 with staggered 525 with 32p 4 blade bravo she will hit 80 at 5200 rpm with trim at 5 on the gage. no problems with overheating. Are you getting good water pressure ?

Sounds to me like you may need transom mount raw water pick ups but i would be surprised if it did not have them already.. The 5 is a lot of prop for that set up i would think a 28 or 30 B1 but thats just a guess on my part, and yes the 28 will bring up the rpm

Props are too big, especially with the extreme high air temps you have. High ambient temps cause a loss of HP.
If you switched to 27" Maximus props or 30" Bravo 4 blades you would see about 5100rpms.
