Causes
A. PRO helm used with “unbalanced” steering cylinder.
B. Mechanical interference.
C. Restriction in hose/helm.
Solutions
A. A SeaStar PRO helm cannot be used with any unbalanced cylinder, this
will result in the steering wheel locking up completely.
B. Mechanical interference (see checks below).
C. Restriction in steering lines or helm (see checks below).
Checks
Mechanical interference:
B-1. Using an assistant, turn steering wheel from hard-over to hard-over.
Visually inspect steering cylinder(s) and engine(s) for any signs of
interference with any other object. Check is to be completed
throughout the trim/tilt positions of the engine(s), including jackplates.
This check should be done while underway as well.
B-2. Tilt Helm Installations
a. Confirm that the steering wheel hub is not interfering with the tilt
cover. Correct as required.
b. Disassemble tilt covers and inspect tilt mechanism for any loose
or separated components. Inspect socket head bolts holding
the coupler together to make sure they are tight and not allowed
to contact any other parts of the steering assembly. Correct
as required.
Hose/Helm Restrictions:
a. Mark and remove hoses from steering cylinder.
b. Place hoses in a catch can.
c. While filling helm with fluid, turn 1 turn to port, then 2 turns
to starboard.
• If the steering wheel cannot be turned in one direction, swap
steering lines at rear of the helm pump and repeat above.
• If the problem moves to the other side, replace that side
steering line.
• If the problem persists, replace helm pump.
4.2 Helm locks up completely
CAUTION!
Any interference must be corrected prior to use.
