Fitment Notice
Confirm fitment by transom assembly model, drive serial number, trim-cylinder style, and hose layout before ordering. Earlier aft-connection trim cylinders and later fore-connection trim cylinders can use different hose sets, even when the manifold block is the same.
When This Part Needs Replacement
Replace the manifold block if it is cracked, corroded, leaking at the hose ports, damaged during hose removal, stripped at the fittings, or causing trim hydraulic fluid loss.
Installation Notes
Relieve trim-system pressure before service and keep the hydraulic system clean. Replace related O-rings during installation, route hoses exactly as shown in the trim-system diagram, and test the drive through the full trim range while checking for leaks.

Parts Desk Insight
This block sits at the centre of the SX trim hydraulic hose layout. The part number matters, but the bigger installation check is hose routing—especially port/starboard and up/down trim lines—because crossed or leaking trim hoses can create hard-to-diagnose trim problems.
