I had one on my Alpha drive on my 18' Donzi. The funny thing is that the only way you know it works is if you don't notice anything. I never had a problem with the top joint in my drive and I was pumping 310 hp through it at 5800 rpm's. For a mininmal investment, it can't hurt. Good luck.

I talked to a few drive guys that said they have never seen a heat related failure in a Bravo drive. However I do run them on my drives along with RedLine Shockproof oil that get's changed every 25 hours.

Like I said, I run them. But has anyone seen a heat related failure in a drive? At least the alpha and bravos have water passages in them for the engine cooling water, the 5 and 6 don't even have that and are running with even more of the drive out of the water then the bravo.

Although the evidence remaining after a failure may not have the immediately obvious characteristics of heat, like the bluish marks, burnt oil, etc., I'd be willing to bet it's a factor in a great deal of mechanical breakdowns that have been attributed to other phenomenon.
Whether, it's only a few degrees past spec of 50*, the effects will show themselves over time. Bearing clearances differ, gear meshes vary, spacing is altered, gear oil becomes more viscous and doesn't protect as well, etc.
You may find a race let go, a shaft twisted, a gear disintegrated, you name it. Some are freak occurrances, bad materials, or some kind of chatestrophic impact...It could also be work hardened from heat(becoming brittle), fatigued beyond limits(fatigue life depends on oscillating stress level cycles and the rigidity of the material--both of which change with temperature).
Energy in=Energy out! The harder you run, the hotter things get!
