Mr Gadgets

Pantera,
Do you know what broke in the XZ drive? Was it upper gears breaking teeth or a shaft? I have seen lots of different things break, due to several things. What were you doing when it broke or shortly before.. Any airborn tactics without throttle control?? Driven with care the XZ should be good for your setup. I have a friend with larger HP and bigger boat with standard Bravo.. 8 yrs on it.. I would suggest going to the XR upper and proper setup. You can break anything they have out there in the Bravo line up, but a properly setup drive should live on your boat...

Hope this helps..

We have a brand new lower unit in stock. It was put on a boat for 20 minutes until I found out the ratio was not what I ordered. I believe its a 1" shorty as well.

I'll post again after I check tomorrow.

It was the upper that failed. We were actually going through a no wake zone when it locked up. The gear attached to the input shaft appears to have tried to push itself through the case.

We were on an inland lake, no rough water or anything that should have caused the failure.

I think I'll get an Imco Extreme or XR upper and have the lower inspected. Hope to get this accomplished by the weekend!!! Loto in 2 weeks!!

Sounds like the pionion gear tooth lodged between gears pushing it out. guess

Problem solved. Ordered an XR from BAM today. Should be here and on the boat Thursday.

Can't understand what happened to the XZ. I baby the throttle until on plane and the boat has never left the water on our inland lakes.

Oh well, welcome to perfromance boating I guess!!!

Thanks for all the input. Rather than rebuild my lower and buy an upper, I just decided to get a brand new drive. I'll rebuild the lower and pick up an upper in the fall as a spare set up.

CONGRATS, Good move XR is a nice drive only weak point is the pinion shaft and with your set up should almost be bullet proof!

We now have 35 hrs on our Max Machine Worx drives, so far so good.
38' Kevlar TopGun with 800+hp blower motors, 11,000lbs+ loaded they also stand behind them for 1 full year.
Good luck with what ever you decide to go with!

I get about 85 hours between breaking something in a fully max machine worx upgraded xr drive,I'm not sure now as i had 725-750hp for last few years and it is signifigantly more now but i have 45 hours on current drive,the last 15 with 950 hp(although i don't have much wot on it yet). The size of prop seems to really determine when a drive breaks,I ran 675 hp thru a stock bravo for over 100 hours with a 26 pitch,went up to 700 hp and a 28 pitch on my 4500lb/27 ft boat and almost immediately sheared gears off. Max seems the best so far although they still do break,if you have serious power its best to have a spare drive if your boating season is short,Smitty

THopefully this one will last a while. Thanks for the info Smitty and your number. I was pretty busy yesterday and just decided to order a new XR from BAM.

I'll get my lower cleaned up with new bearings etc.. and try to locate an upper for a spare.
