Single‑Ram Trim System
GENERAL INFORMATION
The single‑ram (heavy‑duty) trim pump is installed in a remote location, usually
inside the engine motor well. It is available on all offshore models. The
heavy‑duty trim system:
• Is intended for offshore applications.
• Is not integrated into the engine (like the three‑ram system).
• Requires the heavy‑duty (offshore) transom bracket and midsection.
• Includes a trim stop pin to limit the degree of which the outboard is tucked
under.
IMPORTANT: The trim system has no trim out limits. Exercise care that engine
is not trimmed out beyond safe operation limits.
To install the single‑ram trim system, order the the Heavy‑Duty Trim Pump
assembly and refer to the instructions included with the pump for installation.
