Planning to install this winter and fix my broken NXT transmission problem. I hope this is the answer.

The drive is max machine upper with an IMCO lower. Saris pulled his drives apart last week . We are checking ours this week.

Curious how yours looked?

Not sure what you mean, but the DG takes the place of the stock coupler. We checked the DG for runout and balance before installation. The unit was perfect. The stock mercury alingment was too tight, but the drive slipped right in. The DG is custom designed for the particular installation.

Sorry, I was half awake this AM. The drive will be apart beginning of next week. Will post results. As for slip factor. The last run was up the Conn. River. 5800rpm,1.35 drive,24inch prop, 89MPH. Works out to 9% slip. This was with 1300 lbs of passengers and fuel.

Can we work out an OSO volume discount?

The Drive Guardian seems like an innovative idea, just a little pricey!

How much is a typical rebuild on a XR Due to broken gears or snapped vertical shaft?
