This is just complimentary to Marcs outstanding Warpath builders instructions.
Being fortunate in having a pre-built hull, what I am sharing here is just my rigging and set up tricks etc ....
Will make note the engine compartment of the Warpath is tight so MAKE SURE you place engine as far forward as mount & starter clearance allows.
*Using Gizmo/CC type hyperr torque mounts found that some mount trimming was necessary on the starter side mount. Material was belt sanded away so metal was equal in length to diameter of A/V rubbers. ( this allowed me to place A/V rubbers within @ 1/8" of forward bulkhead )

When first setting and finding engine location simply placed engine with A/V's onto mounts lightly tightening them down.
Drew a line just behind the dowel pins set in bulkhead on tub so I knew from the outside where it's edge was at.
Then on the outside of tub set engine against it and looking down upon it set spacing of engine off bottom skin, made sure starter side mounts were as forward as practical and drive angle wanted. Then took a pencil and drew circles around A/V mounts drawing onto tubs side. ( Note line shown in pic below )
Measured 3 times making sure position chosen was correct and spacing distance of A/V mounts was correct front to back before drilling any holes.
That done placed A/V rubbers into hull doing a trial fit .... Got lucky with a perfect fit
Next was getting stuffing tube and log fitted into the bare hull.
*Taking a short piece of 1/4" brass tubing placed it into cable collet then slid it out slightly so it was just shy of contacting bulkhead. Rotated engine slowly making sure adjusting run out so tube rotated with engine having no wobble.
Once satisfied drew a pencil line around most of the tube.

Taking a 90* drill and starter bit drilled the pilot hole followed up by a 11/32" hole which is the O.D. of the log tube that be epoxied into hull permanently.
** Now here you need to pay attention to what your doing because next we are making a SLOT out the tubs bottom
In this process I use misc short lengths of the same diameters of K&S brass that will make up the final parts. 1/4" shorty used on engine collet, 5/16" .029 wall shorty that is the stuffing tube, then a piece of the 11/32" which is the log.
*Now I slide a piece of stuffing tube onto 1/4" having it pass threw hole in bulkhead. sliding the tube down a bit has it hit floor of tub (
DRAW A LINE )where it hits. Then with short straight edge or anything straight, set it on top of tube and takes it's top edge down until it hits floor of tub (
DRAW A LINE ) *This is the APPROXIMATE starting and ending position of slot
I just use a 1/4 diameter burr in a die grinder and plunge out the forward and reward positions then cut between them roughening out the slot.
Then using a ratt tail file slowly widen the slot to 11/32"
making sure slot stays on tubs center line. I do trial fit the 11/32" tube time too time getting width just right. Length of slot fine tuned until the 11/32" tube go's threw the slot and slides over the 5/16" stuffing tube shorty still on the 1/4" shaft in engines collet. Once done it is a PERFECTLY ALIGNED straight shot for cable.

Next cut the 11/32" log tube at length required, roughen it up with some 50/80 grit sand paper and epoxy it into position ..... Done !!
( I do mix chopped up fiberglass into the epoxy adding strength )
Bottom of tub around log once positioned sealed with some masking tape while doing epoxy inside, then a finger blended in fillet of epoxy added as last step on outside of tub where shaft log exits.
Next using a 5/32" extension drill placed holes threw the transom and 2 bulkheads for the 5/32" water line. (I'm using a right ride rudder so placed water down left side ) Dubro barb ends soldered on both ends once tube epoxied in place.
