MANUFACTURER’S MANUALS
It is important that you read the manufacturer’s engine
manual carefully and become completely familiar with the
operation as well as necessary maintenance on the engine
and propulsion systems. Your Regal dealer has been factory
trained on all Regal boat systems. Consult your Regal dealer
for further information regarding technical issues and parts.
Use only approved marine replacement parts.
ENGINE MOUNTS
The engines are placed in the boat on a set of metal or
wooden platforms called mounts. These rubber isolation
mounts keep the engine from moving laterally and
athwartships (right angles to the center line). The mounts
help reduce the vibration caused by the engine and drive.
Periodically, the mount hardware should be checked for
tightness.
ENGINE ALIGNMENT
Mercruiser stern drives use a rubber splined hub to which
the stern drive shaft is attached. There is an alignment
specification between the engine and outdrive that needs
to checked periodically. A special alignment shaft is greased
at the tip and inserted through the gimbal housing.The
alignment angle can be determined by the spline image
left on the tool. The engine mounts are then adjusted to
permit a similar spline image 360 degrees around the
greased alignment tool. This specification should be
checked after each 50 hours of operation or if the vessel
has run aground or hit a submerged object. Alignment
should be checked by a Regal dealer or marine professional
since a special tool and procedure is required.
ENGINE REMOVAL
In the event the engine requires major service and needs
to be removed, consult your Regal dealer. The dealer
posseses the knowledge and factory training necessary to
accomplish such a job. Do not undertake this type of repair
yourself.
AVOID SERIOUS INJURY OR DEATH!
READ ALL MANUFACTURER’S ENGINE
AND PROPULSION OWNER’S MANUALS
