ORDERING GUIDE (CONTINUED): CATAMARAN
NOTES:
* See SeaStar Outboard Pivot Mount Cylinder application guide earlier in this catalog for some engines which may require HC5347-3,
** When using two HC5370-3 cylinders, the rods must face each other.
*** For HC5345-3, HC5347-3, HC5348-3 and HC5358-3 cylinders, tie bars vary by engine make & model (see application guide in the SeaStar
Outboard Pivot Mount Cylinder section) or use engine manufacturer’s tie bar.
For dual engines with engine center distances from 26-36”, use the appropriate SeaStar tie bar. For dual engines with center distances greater
than 36”, obtain longer tie bar, use HC5343/HC5374 cylinder with drag links, or use “Hydraulic Tie Bar” system with SeaStar Alignment
Valve.
For speeds over 55 MPH, use SeaStar PRO helm #HH5770. (Must NOT be used with single side mount [unbalanced] cylinder.)
For information on additional steering stations or other optional helms, refer to the ordering guides in the SeaStar Outboard Pivot Mount
Cylinder and/or Side Mount Cylinder steering sections.
SeaStar Power Assist (P/A) is an option for most of these systems. For SeaStar helms, use SeaStar P/A systems; for SeaStar PRO helms, use
SeaStar P/A PRO systems.
ALIGNMENT VALVE FOR HYDRAULIC TIE BAR
(WHEN A MECHANICAL TIE BAR CANNOT BE USED)
The SeaStar® Cylinder Alignment
Valve (part #HA5471-2) will allow for
the periodic required realignment of
two outboard motors or rudders that
are linked together with a Hydraulic
Tie Bar as opposed to a solid link or a
Mechanical Tie Bar.
A standard helm and SeaStar hoses
may be used on vessels not exceeding
speeds of 55 MPH. Boats exceeding 55
MPH must use the SeaStar Pro Helm
Pump (part # HH5770) and SeaStar
Pro Kevlar® Hoses.
