On dual or triple engine high speed applications, Mercury MerCruiser recommends the use
of a Quicksilver Priority Valve Kit (Part Number 79691A4). This kit allows two power steering
pumps to be used and helps to ensure that power assist will be maintained if one engine
or power steering pump should stop functioning (engine runs out of fuel, etc.).
ENGINE MOUNTS
The 454 and 502 models come standard with heavy-duty pedestal-type front engine
mounts. These mounts include provisions for isolating engine vibrations and can be used
in most sport boat applications. On offshore boats or boats which will be used in rough water
areas, however, Mercury MerCruiser recommends the use of a solid plate engine mount.
Multiple Sterndrive Steering - Tie Bar Arrangements
With multiple sterndrives it is important to consider which of several possible steering sys-
tems should be selected.
CAUTION
Failure to observe the recommended Tie Bar Arrangements could result in serious
damage to the steering and/or trim system components. This damage could ad-
versely affect control of the boat.
INTERNAL TIE BAR ONLY
At the lower end of the performance spectrum (boats not capable of speeds in excess of
60 MPH) the basic internal tie bar is recommended. It connects the slave sterndrive to the
sterndrive that is directly connected to the factory power steering output. This internal tie
bar is available in a variety of lengths from the sterndrive manufacturer.
