Smitty,
Thats sucks!! I was hoping that this process would have been the answer. I know that Dave ( ZT260 ) has had good luck with his gears from Dean. He will be putting alot of hours on his boat the next few days. I am sure we will get an update by mid-week.

New update,drained oil last friday to install drive spacer,no metal,drive spacer wouldn't fit due to the design of the tower base max worx uses. Put lower back on the same way it was,ran boat at pt huron/st claire on the river for a couple of real hard 1-3 minute 5900 rpm runs with 30 pitch prop last weekend,took boat out during week and made about 6 real hard passes with 32 pitch,drained oil yesterday to install drive spacer (I had it custom machined to fit this week),was FULL of metal. Tore lower down,it has about 20 hours on it since gears were installed,pinion gear (the small one) is pitted real bad,driven gear looked ok. Funny thing was I been using 85/140 royal purple,never heard the normal noise drive makes when gears are getting bad and the lower bearings weren't scarred or damaged at all. I think the oil must have masked the noise and somehow kept metal from scarring up the bearings. I threw a set of stock gears in for now and have it back together.The extra stress from the 32 pitch must have helped do the gears in.So I would call this experiment a failure but it was something I wanted to try.
I'm open to suggestions for the next experiment,what do you guys think I should try next? I could get a set of gears cryo treated or heat treated THEN cryo treated,buy a set of treated gears from the bravo shop that they are putting in the b-max lower if they are available yet,buy a set of treated gears from max worx or buy there newest thing,lower gears they are making from 9310. They are still testing the 9310 gears as they just made them plus they are only available in 1.22 or 1.30-1,not 1.50-1 so I would have to buy a 28 pitch labbed prop. Looking for your opinions and input,Smitty

Smitty whats the price of these gears compared to the Merc stuff. I was thinking dealer on the Merc gear set was 200 something. The Bmax gears are just a coated/treated type gear ,he doesent have the helical gears yet.
and I dont have my new drives yet either

David is still testing his new BMax lower gears, I think he has about 20hrs now at 1000hp
