Washing
After using in salt water or dirty water, wash the Hobie
MirageDrive with fresh water. Allow to dry, then spray metal
parts with WD-40™ or equivalent. Special attention should
be paid to threaded cable ends, lock nuts, chain, shafts, ped-
als, and adjustment pins.
Cable Adjustments
Determining if adjustment is needed...
Occasionally the cables may need to be
re-tightened. The cables should be kept
taut; however, the front chain should be a
little tighter than the rear chain. Push with
your thumbs at the points marked (A)
with moderate pressure (see the image
to the right). The side of the chain should
not go beyond the inside edge of the
drum casting.

Drum Casting
When turning the nut with a 7/16 inch
open-end wrench, only giving it one half
a turn at a time, then do the same to
the remaining three nuts. Re-check the
tension and adjust accordingly.
Note: Keep the pedal shafts and masts parallel. When the
shafts are together, both masts must be straight down. The
idler pulley cable (see item B in the illustration below) will
be tightened automatically when the front chain assembly is
tightened.
Miscellaneous Maintenance
Periodically check for loose screws or frayed cables. If a
cable has a broken strand, replace it with new cable.
CAUTION
Care should be taken to avoid striking objects with the
Hobie MirageDrive. If you bend a mast, it usually can be
straightened. To straighten, remove the MirageDrive from
the boat and insert the Drive into something solid, such as
a vise. Remove the fin, then carefully bend the mast until
straight. To test for "true", roll the mast on a flat surface and
straighten as needed until the masts roll evenly. If the mast
cannot be straightened or becomes cracked or fatigued,
replace the mast.
