Hi guys. Will be putting Stelling extension boxes on a 1999 382 that was not rigged with them from the factory. Does this pose a problem with my x-dim and drive depth? Is the x-dim raised at the factory when a boat is rigged with extension boxes? The drives are stock length IMCO extremes. Any help would be appriciated..

I know Formula did a lot of experimentation to arrive at the optimal X-dimension on the 382. I think one would be wasting a lot of time and money trying to change it from factory specs. I refinished my Stellings a few years ago and reset them to factory height. Hope some of these photos help. You can always check with Formula TAG ... they are always very heplful with techincal questions like this.

I hope it's the same, I don't have time to do the transom in that thing to raise it! Lol good luck!

I'm willing to bet the transom cutout is the same. Mine are on the center hole of the three for height adjustment. Can't get a measurement for you right now as the boat is in my building in Ohio, but I think it was 3" from the notch to the bottom of the Stelings box.

So if anything is different it's in the box not the actual crank centerline height in the hull

Correct, but I wouldn't use the bottom hole. That tends to be hard on drive shafts.

Kreed, you should send the boxes to Stellings to have them aligned while they are off.

Lets see some pics of the new ride.

He should leave them where they are and save any and all aggravation ! Just looking out for your mental health Kevin! Don't want you to get stressed out!

Thanks for the help... azz-end looks nice! You running dry exhaust?

Jamie, Ive been stressed out for 3 months! Just about done now, less than a week and I should be able to breath. Boxes are worth 3 MPH, theyre comin with me! haha.....enless you got some 10-71's you want to trade? Ill make up the speed somehow!

Matt, thanks,I will send them out. Didnt realize that was part of the maintainence. Ill put them on in neutral hole. Just wanted to be sure holes cut in transom werent in a different location with or without the extension boxes......I want to run dry exhaust on this boat....the engines should sound pretty good dry! Pics to come soon.
