Shaft with flat spot for drive dog screw.
Drive dog, prop and prop nut in place.
When cured, sand with 150 and recoat with
epoxy. This coat will use far less resin than the
first.
When this cures, wet sand the bottom of
everything with 220.
If you are painting sand the entire boat with 220.
Now is the time for primer. Wet sand the primer
with 400, and use spot putty to fill any
imperfections. Wet sand with 400 and lay on a
heavy coat of primer. Wet sand with 600-800 and
paint.
Use fuel proof paint or fuel proof clear.
Final Assembly
Bolt the strut to the transom. Make sure that the
strut is straight up.
The strut needs to be at the very bottom of the
ski for the proper propeller depth.
Make the ski parallel with the bench (0 degree
angle).
Slide your drive dog onto your flex shaft, then
your prop. Leave about half of the threads
showing past the prop.
Tighten the drive dog set screw.
Remove the prop and measure the exact location
of the set screw from the end of the shaft.
Remove the drive dog and file or grind a flat spot
on the shaft about 1/8 inch wide. Put the drive
dog back on the shaft, aligning the set screw in
the flat you made.
Push the flex shaft into the shaft tube, and into
the collet. Make sure that the shaft goes all the
way into the collet. Measure the distance from
the back of the strut to the front of the drive dog.
Subtract 1/4.
