Stuffing tube
Set up for surface drive, this will exit the rear of the
boat, through the transom.
The stuffing tube is a piece of 5/16 brass tube.
Drill a 5/16 hole at the bottom of the transom. Make
sure it is centered. Open up the hole in bulkhead 4
if necessary.
If using a Zenoah engine, the center
of this hole should be 1/2 inch up from the
bottom of the boat.
Cut your brass tube about 17 inches long, and
make a mark about 2-1/2 inches from one end.
Heat the tube with a propane torch, at your mark,
for about 3 inches until it changes color.
Let cool.
Slide your 5/16 brass tube through the holes, and
out the transom, slip the ¼ cable inside. Carefully
bend the brass tube where it was annealed to
roughly match the engine collet. Make this a
gradual, large radius bend.
Set the engine between the rails, and see if the
cable will slip into the collet.
If you can angle the engine and get the cable to slip
into the collet,
it’s time to mount the engine.
Set the engine between the rails and try to center
the carb in the cutout of the engine rail.
If you are using an engine other than a Zenoah, the
target CG is 34%(15-1/2 inches) percent of the hull
length, measured from the transom forward.
Put the engine in place, and make a small mark on
one of the engine rails.
Use this mark as a guide to mount the engine.
This may require 3 hands…
With the stuffing tube about ¼ inch from the end of
the collet, angle the engine so that the cable is not
strained too much. Make sure you are near your
mark from the transom.
While holding all of this, use a short, sharp pencil to
