I've really been thinking about the problem you are having with the lower gears. I think some of wear is from the propshaft deflecting/twisting. (plastic deformity)
Notice a Speedmaster lower, like a #6 , The majority of the propshaft is supported by many caged needle bearings that are lined up, not just 2 or 3. Maybe a change in bearing carrier design to add more support to the shaft, and the wear will decrease. BBB

I think if that was the case the gears would hold up better in my spare drive that has bigger xr max worx shaft and billet prop carrier. I'm going to try running 140 wt gear lube from now on too and see if that helps. I was running some exoctic
stuff max worx swore by but they wouldn't tell me the weight. Motor is swinging in the air right now,inspected the upper in my drive fri night that is going to be on boat for the test,gears still look like new. Bought angle finders,stainless bolts and longer water hose fri,hope to have motor sitting back in boat and lined up by tommorrow night with the stellings box on,Smitty

Update on gear experiment-I have ran boat 6 hours now,hasn't spit teeth off lower gears and NO metal in lower unit oil YET. I have only ran it at wot though for a few 15 or 20 second burst but have cruised at 4000 rpm's with 30 pitch 4 blade. Hope to whip on it a little this weekend and see whats going to happen,Smitty

I'm not a wrench, and not very educated when it comes to these kinds of things -- but I do like staying on top of the technical side of things, and becoming informed on what I can, just in case the info comes in handy down the road.
I just had my upper gears let go two weeks ago on my Bravo Ix. Max inspected the lowers and said they still had life left -- which to me means I'll be buying lowers soon. So, I'm diggin' this thread. Fascinating.
