Strut cut back, and mounted on standoff blocks. Omit block for Z21.
Ski being test fit.
Strut
Mount your strut to the transom using
center marks to align it. Make it so that
when the strut is in the middle of its
travel, the bottom of the strut is about ¾
inch below the tub bottom.
You may have to adjust the shaft tube
some more.
If using the Zipp Z21 strut, the spacer
block is not needed.
The strut needs to be at the very bottom
of the ski for the proper propeller depth.
See drawing below and trim the front of
the strut if needed.
Test fit the ski to the tub.
The rear of the ski should line up with
the rear of the transom, and the front
should blend into the tub bottom. Sand
the front of the ski sheeting so that it
blends to nothing.
Be sure the shaft tube is just touching
the ski sheeting, and level with the tub
bottom.
Measure from both sides and make
small alignment marks for the ski.
Using 30 minute epoxy, seal the bottom
of the tub in the area of the ski, and
epoxy the ski in place. Be sure that the
inside of the ski is sealed with epoxy.
Tape and weight the ski, check
alignment, and allow to cure.
