I like Amsoil Severe Gear 75w110 full syntheteic,, change it every 20-30 hours.

I try next Years an 662 SCi with an complett new XR and mount an Driveguardian on 27er Baja!
I am pretty shure to get no problems with this setup next years!The DG is an very good option for this combi i mean.
Best regards.

38 top gun 750 pfaff. 12 hrs lost port drive. Lol. Looking at options now. . Maybe a eliminator

Arneson conversions

But that extrem much Money for 2 Drives!
At 750 HP i would go to Driveguardian at the engines and Bravos Drives or some stronger ones from other Companys.I was wondering why not more guys take driveguardion when they give more Power to an XR as it is ok for him.Think this tool helps much to break not the shafts and gears!
By the way,i have 2 new from merc XR in orginal box with gurtante,but they here in germany!
i sell for 5000 euro,maybe 6000$.
How much is a complett swap to Arneson drives???
Michael

What ratio are the drives, and what would it cost to ship to the states ?

They are 1,50,dualwaterpickup and Seacore version.2 year gurantee for Buyer from merc,as absolut new in orginal Boxes! Bam sell this Drives for 9998 dollar on ebay.com!
see Link!
I dont know how much shipping is,but its also with shipping best price for an XR i think!

about 50k if you have someone do the swap

But then you have no breakage up to about 1000up, smooth shifting with a trans,less drag,built in standoff box putting yours leverage and props farther aft,full hydraulic str included,heavy duty tie bar,trim pumps,etc. Only way to go at that level until you get to merc #6 territory which is a lot more money.

Any bravo type drive will not work from 650-900
