DRIVE SYSTEM AND ENGINE INSTALLATION
Alpha Trim Cylinder Disassembly
On some boats, increased trim‑in range can cause handling problems at high speeds, resulting
in personal injury or death. We recommend that only qualified personnel adjust the trim‑in limit
inserts and test the boat for handling problems.
Contamination can damage the hydraulic system or cause the system to malfunction. Failure of
power trim or steering components can result in injury or product damage. Ensure that the work
area, shop tools and all components are clean and lint free during reassembly.
IMPORTANT: During service procedures, clamp the trim cylinder on the front mounting flange.
Clamping the center section of the trim cylinder can cause damage.
1. Remove plug previously installed, if applicable.
2. Remove end cap with spanner wrench and remove piston rod assembly from cylinder.
