I had a few suspected problems but everything is fine, I have about 10 hours on the drives

I had a binding issue on one lower unit and some shavings in one upper. The binding was because the lower was not mounted on the upper and the thrust bearing was moving up, the shavings were thought to be machining spirals that "accidently" got inside the drive. Check out this link, near the bottom I have details about the problems. http://www.offshoreonly.com/forum/sh...threadid=19744 So far they have worked great.

How much power are you pushin through them?
I see you have the 28"s on there...What speed and rpm is it turning.
Hope thats not too personal of questions
BTW, they are here and they are spectacular!
I noticed some weld circles on the lower...maybe from manufacturing?
Here is a pic of the 2"shortie lower next to a stock Bravo.

The weld circles are normal, Mine has them too, They get worse when slightly corroded. Just keep it polished. I am going to try the Zoops seal and see how it works to keep them bright. The 28's I have were severely cupped and running like 32's. They are at hydromotive right now being re-worked. I tried a set of 30's last weekend and was turing about 400 RPM higher than the 28's at 50 Mph. I have not had the chance to do a speed run yet with the 30's. I maxed out the 28's at 81Mph at 4500 RPM But I need to spin them faster. When they get back I will test agian. My engine builder says I should be running 1.50 gears as to not load up the drives. At this point I am still testing and IF I need to make the change I will.

I am running about 680 Hp into them. So far they have been great.

I also have the heat spots, I have tried just about everything to get them off, have done a lot of buffing and polishing,they are still there. Guess that if you can see them"you are to damn close!!"
If you find a way,let me know!!

I am going to be running 125 gears with 30 props to start with. We go to the dyno next week with two new 540's that should make 800 plus easy. The new sc drives came in wednesday and look really nice. Hopefully we will be in the water in a couple of weeks.
