I just bought a steering kit and I would like to add a friction screw to the system, but
none was included with the kit. What should I do?
I just bought a steering kit and I would like the steering shaft to be at an angle to the
dash. The bezel kit included in the steering kit only allows a 90° mount. Which parts
do I need?
Friction adjustment is not a standard item in our steering kits and is not available for Rotary Systems. If you
have installed a non-tilt “Back Mount Rack Helm,” order Friction Kit part number SA39531P.
NOTE: If you have any NFB system (Rack or Rotary), a friction adjustment device is not required nor
The standard Bezel (mount) Kit included with the steering system allows the helm to be installed at 90°
(perpendicular) to the surface of the dash. Optional Bezel Kits for Rotary Steering systems provide the
ability to mount the helm at 20° from perpendicular. The Rack and Pinion system uses “Wedge Kits” that
provide 10° and 20° angles.
For Rotary Steering (Safe-T QC, NFB Safe-T II or 4.2), order 20° Bezel Kit part number SB27483P.
For Rack and Pinion Steering (NFB, Non-NFB, and Pro Rack), order: 10° Wedge Kit part number SB27448P
or 20° Wedge Kit part number SB27449P.
Generally, replace rotary with rotary, rack & pinion with rack & pinion and hydraulic with hydraulic. Rotary
helm gearboxes are round in shape. Rack & pinion helms are tubular and connect to a long, thin metal
rack housing. The following is a brief cross reference for the most popular non-SeaStar Solutions systems:
Morse® Command 290™ Rotary: use SeaStar Solutions HPS or Safe-T QC for power-assisted
or NFB 4.2 Rotary for non-power-assisted. (Some Morse® Command 290 products are still available.)
Morse® Command 200™ Rack: use SeaStar Solutions Back Mount Rack for power-assisted or
NFB Rack for non-power-assisted and The Pro Rack for dual cable boats.
Morse® Command 2™ Rotary: use SeaStar Solutions HPS or Big-T for power-assisted or
NFB Safe-T II or 4.2 for non-power-assisted.
A comprehensive steering interchange listing (with illustrations of helms and cables) for SeaStar Solutions,
Morse® and other brands begins on page 9 of this catalog.
SeaStar Solutions does not make specific recommendations regarding steering wheel size, except that
the wheel be at or below the maximum wheel diameter noted for each type of helm and that the
wheel is sized/located so it can be rotated freely by the boat operator through the entire steering arc
with no obstruction or hindrance to movement. Wheels in the 14" diameter range are used widely with
mechanical steering systems. Any size wheel may be used so long as the helm’s recommended maximum
wheel diameter is not exceeded and steering effort is acceptable.
An “equidistant-spoke” steering wheel is suggested for hydraulic steering systems since a certain
amount of oil bypass in the helm will gradually result in the wheel becoming “not centered” when the
engine/drive/rudder is in the straight ahead position. Again, please note the maximum wheel diameter
recommended for the helm.
NOTE: For mechanical steering, please note the maximum wheel diameter listed for each product earlier
in Mechanical Steering section of this catalog. For Hydraulic systems, maximum wheel diameter is listed
for each helm in the SeaStar/BayStar/Hynautic Helm Specifications chart in the Hydraulic Steering Tech
Reference section.
I need to replace the steering system on my boat, but I looked at the back of the helm
and saw it was not made by SeaStar Solutions. I want to install a SeaStar Solutions
system, but how do I know which one I should get?
What size steering wheel should I use?
