fast 252,

I have! I also have the Stelling's extension boxes. I have 50hrs on my drives and driveline withOUT the drive savers. Your driveshafts will need to be about 1/2" shorter or so (I can't remember the exact measurement), so you may have to have your driveshafts shortend, but that will depend on how much clearance you already have with them the way they are now. I have just installed the drive savers, but had to have the drive shafts shortend to make the fit.

My extension boxes have been mounted as high as I can get them for my particular make of boat which is just underneath the rub rail. I suppose it could be mounted above the rub rail level, but I didn't want to interfere with the rub rail so I may have to have some IMCO 2" shorty lowers installed. I think my driveshaft is at about 6%. I guess the most you can safely go is 6-7%. I'm not sure what clearance you're talking about.

kaama-I had the same problem as you. The rub rail would not allow the extension box to go high enough-even with a 2" shortie. I had my brother in-law machine a piece of 1-1/2" aluminum plate to form a spacer. This pushed the box further away from the transom and a notch allowed it to fit nicly over the rubrail. Eventhough the plate is aluminum, it still weighs a pretty penny and wasn't cheap to buy-but it got the job done. The best thing is that I didn't have to extend the drive shaft.

What is a drive saver?

I forget exactly how it works, but it's along the same lines as a whirl-a-way.

Marty, A draw back of using a Stellings extension box is that you can NOT use the stock Bravo drive coupler, and because of this, there wasn't anything available from Stellings to absorb the shock/vibration/dampening effects from shifting, drive re-entry, etc. So there is a company that makes what is actually called a "Drive Saver" that is donut shaped and is made out of some sort of heavy-duty, super strong plastic/nylon material. Stellings does send there own coupler when you buy their extension box, but it is made out of metal---but you'll need to still use this in conjunction with the Drive Saver. Thing is, is that you will need to take the driveshaft to a business that shortens driveshafts.

Did you buy your drive saver from Teague Marine $225.
do you know of any other mfg`s and how well do they work...?

So do I need one for my stelling box? Do all the skaters, formulas, etc from the factory with stellings box have one? Is this a real fear/concern? to need one? Where do I get one?
