Before Starting

Carefully study this manual and ALL other manuals provided with 
your SeaStar Steering system to familiarize yourself with all of the 
components and their intended, or required mounting locations.  
Ensure that there is adequate space available for installation of all 
components and easy access for service. It is good practice to 
mount all components before installing hoses. This allows port to 
port connection with less chance of an error. If you must run hoses 
first, a system of marking the various lines must be used. ALL 
hose ends must be closed with tape or similar material to prevent 
contamination. CONTAMINATION IS THE MOST COMMON CAUSE OF 
SYSTEM FAILURE.
Read ALL bold print text, notes, cautions and warnings. Reading them 
now will help prevent unexpected surprises during the installation.
These instructions have been made as complete as possible, and 
as brief as practical. If you have any questions, please contact your 
Distributor or SeaStar Solutions for assistance.

•  1/2”and 3/4” open-ended wrench.
•  Wire cutters, crimpers, soldering iron.
•  Screwdriver for attaching mounting plate.
•  All other tools noted with your helm pump and steering cylinder 

installation instructions.

Tools

Failure to follow these and ALL other installation instructions may 

cause loss of steering control leading to property damage, 

personal injury and/or death.
