im looking into buying one of them outboard motor mounts that put the engine 9 inches out.. would this evenly distribute the weight?? and rtrhen i would by an extended tiller arm.. worth the try?????

I think what you are refering to is a jack plate.   They come in different off sets, from 4" to about 10" back, some piggy back two units and go even farther back.

A couple of things to consider, one is the boat's warrenty, gotta make sure you're not voiding the warrenty, some manufactors don't allow them, some limit the amount of set back you can have.

In general, almost any hull can benifit from one.  They make it much easier to get the engine height dialed in and the extra set back makes it easire for the motor to lift the bow.

There are some drawbacks also, if it's an older boat and the transome is questionable, you could rip the motor right off the boat.   Just about any size you put on a fiberglass boat is going to increase the number of stress cracks back near the motor.

I wouldn't even think about it if I was running a tiller motor!

If you decide to do it, with the tiller arm extension, make sure you take video's on your first outing. I'd really like to see that.  

Dang, looked right over the fact he was wanting to do this with a tiller motor.  My first thought on that is "WHY????????"   Gotta figure you're talking less than 40 hp, since that's about the max a tiller motor comes in.  Just hard to imagine getting much performance gain from a boat running a small tiller motor.
