RE-GREASING THE DRIVE SHAFT:
1. You are going to need one 10mm open end wrench and
one 12mm open end wrench and some grease.
2. To loosen the cable coupler hold the 12mm wrench still
and turn the 10mm wrench counterclockwise. To tighten turn
the 10mm wrench clockwise.
3. Slide the shaft out from the back of the boat and re-grease.
Reinstall and retighten the cable.
TUNING TIPS
STRUT – The strut on your UL-1 can be adjusted up and
down as well as tilted. To adjust the strut you are going to
need to loosen the 4mm bolt that holds the strut in position.
When making a strut adjustments you only need to move it a
small amount at a time.
Lowering the strut helps stabilize the boat by lowering the
nose of the boat. However, doing so can slow the boat down.
Raising the strut has the opposite effect. Tilting the strut is
helpful to tune the hull to a particular propeller. If your prop
is causing the back of the boat to hop up and down (unhook)
try removing or lessening the drive angle. If the boat seems
pined (stuck to the water in the back) try adding some drive
angle. I like to adjust the strut to the point the back of the
boat just starts to hop and then move the strut back just a
small amount to stop it.
RUDDER – You can tilt the rudder fore and aft to change the
way the boat handles. The more you tuck the rudder under
the boat (negative angle), the tighter the boat runs on the
water. Tilting it back (positive angle) causes the back of the
boat to run looser. You don’t want to overdo it so just work
within the amount of movement provided by the bolts. Also
the more you tilt the rudder back the less aggressive the
steering becomes.
