Any updates on these? I am looking at ordering a pair of lowers and find mixed reviews. Most negative reviews seem to be from people that never tried them and just keeping saying "china".

I have had my SEI lower for 10 years, maintenance is key to longevity.

Stock power? I bought a couple sets of there Bravo lower gears to experiment with, tried a set in a 27 fountain with a 500efi, that was a mistake!

Sounds like they failed as fast as Mercury lower gears?? Haha

why do you think that is? Tons of people have had lowers for years without a problem.

my thoughts exactly, it's not like mercury's. Got a good track record with their out drives.

I have found if you keep them on an outdrive stand, they have even better longevity!

Finally go around to popping the cap off my new in 2020 Bravo ones. I installed them the same time I installed the 700HP BBC. All the gears were in normal looking condition with no slop anywhere. Nothing on any of the magnets either. I know I could go out and break em tomorrow with the power I have but a little restraint I'll put money on these drives lasting 500+ hours. 140 currently and still looking good.

I think SEI is hit or miss. As in I'm sure there is bravo 1s that they make that will last for ever, and others that come out of the exact same factory that will last a day and then break. I just had a 3 year old SEI optimax lower in that both drivehaft and prop shaft seals wasted, and the driveshft surface worn to the point it could no longer seal.
