I built a 850hp blower motor last winter that went in a 29 Warlock World Class. Installed a drive guardian and a XR drive. About his 3rd trip out with the boat, it broke a tooth off an upper gear while getting on plane. Not blaming the DG at all, I think they are a wonderful piece, but the gears can still break. I doubt that he was anywhere close to max torque when the gear broke, therefore the DG could do nothing for him.
On a brighter note, I installed a new XR upper and he beat the snot out of it the rest of the summer with no failures.

get someone that has a twin engine Bravo app - and if they are buying the DG install one only. Maybe OSO members donate some money to the person doing the testing. If we had 100 people and each gave 50 to 100 bucks person that would be 5 K to 10 K. Find a trust worthy person with a twin Bravo app - and both bravo's apples to apples time on them or even new. Just saying

I believe thats why they sponsored 4-5 raceboats. Ours being one of them. Whats the difference between a year with DG versus a year without DG and running one engine with one engine without, BUP? We ran the same schedule, props, engines, competition, ect.

I’ve only opened up one drive after it had a dg installed, showed the same wear on the gear set as it did before. In this instance it is not extending the drive life, but this particular boat didn’t tend to break parts before. Just wore the gear sets out

The harder you run, the more benefit you'll reap from the DG. Sounds good to me

Hello
I have mount my engine yesterday and use alignmend tool from merc to adjust!
I can pull in and out of the Dg with one finger
Today i try to mount an XR new out of the Box but i get no chance to mount.
Can pull maybe one inch in the DG and end. I checked 3 time if all is clear with adjustment and found nothing wrong!
I then look for the inner diameter of the DG and found out it is nearly 1mm more (put 26,6mm nut in) than the merc tool(25,7mm) to adjust the motor!
I am pretty shure that the adjustment from the engine is the problem as with merc tool that is so small its a toygame to adjust the engine right!
what way have you adjust your engines with DG?????#
Hope i can get fast help to make my boat ready.!

Alignment with merc tool was perfect!I can hold with one finger and slide in and out!
But new drive will not fit.No wonder as there is a diffrence from 1mm from tool to DG!
Problem is i have no old shaft in fast time here! real a problem for me know!****!
