1. Remove the cabin and
turret from the hull, place the hull upside down on the bench. It is a good idea to pad
the bench with an old towel or blanket.
2. Draw two lines down the
bottom rear of the hull. These lines should be parallel to the keel and 1 11/16" to
either side of the keel. These lines are the centerlines for the rudders, struts, and
shafts.
3. Drill two 5/32 holes for
the rudder bearing tubes 1-11/16" from the transom on the shafts center lines. These
holes should be vertical to the water line.
4. Scuff the rudder tubes
with sandpaper (1/8" T.D. x 1 3/8" long) then tap them into the holes you just
drilled. Leave about 1/32" of the tubes exposed. Zap the tubes in place.
5. Install the struts as
shown in figs. 2 & 7, don't forget the reinforcing ply inside the hull. A little trick
that we use to line up the struts is to place,a shaft in the strut and line the shaft and
strut up with the line drawn on the hull. We then "Zap" the strut in
place. After removing the shaft we drill for the mounting screws. We leave the strut on
the hull for painting.
6. Insert the shaft back in
the strut and push it forward until it contacts the hole. Use this contact point as a
guide for the hole for the stuffing box tube. The hole should be enlarged a little bit at
a time until the shaft will pass through. Slide the shaft up through the hole and mark the
interior frames for clearance for the shafts and stuffing boxes. Now carefully enlarge the
shaft holes until the stuffing boxes fit. The shafts and stuffing boxes must be carefully
aligned with the strut or battery life will be very short. |

 and get it right. We generally make the hole in the hull about
1/16" oversize then use toothpicks to shim the stuffing box into the correct
position. If you have not already done so, scuff up the stuffing box with sandpaper then
tack the stuffing boxes in place with 5 minute epoxy. When the epoxy sets, recheck the
shaft for freedom from friction. if it is okay, finish bonding the stuffing boxes to the
hull with a paste made from 5 minute epoxy and microballoons.
7. We cut our shafts down to
16" in order to keep the motors low in the hull. The shafts can be cut with a dremel
cut off wheel or a triangular file.
8. Mount the motors as shown
in figs. 2 & 7. Note that they are mounted parallel to the water line when viewed from
the side to keep the weight low.
9. Cut down the rudders as
shown in fig. 7 with a hacksaw and sand smooth. Install the rudders in the hull as shown.
The rudder arms are a little awkward to get to but we couldn't figure out how to keep the
hatch inconspicuous any other way.
10. We mounted our radio
gear up at the very front of the open area in the hold and carried the battery (Dumas
#2024) just aft of the rear of the deck opening. The actual placement of the radio and
batteries can vary considerably. Place your radio gear and batteries where they are
accessible and where they cause the boat to float properly in the water. |
