Purpose
A new trim assembly has been released for SX-A and
DPS-A sterndrives. This new design is now used to
service earlier versions of these products.
The trim line mounting is different on the new assembly.
To use the new assembly on earlier products the trim
lines must be changed to the new design. All of the new
service kits contain the new trim lines.
There are two kits offered and covered by this
instruction, a Cover Kit and a Trim Pump Kit.
All information that follows refers to the diagram on
page 2. Diagram A is the existing, earlier trim system,
B is the new design trim system, included in the kits.
Complete trim system kits are also available. See
Workshop Manual 7746477 for installation instructions.
