Engine & Controls
CHAPTER 3

Ethanol in fuel is a strong cleaning solvent that can clean fuel system
gum and varnish. As a trade off these released deposits can clog fuel
system parts such as lters and engine fuel injectors.
Do not use ethanol blends greater than 10% such as E-15 to E-85. Your
marine engine may be damaged by more than 10% ethanol. This type
of fuel can cause a loss of performance, starting problems, serious fuel
system and engine damage.
WARNING
!
Always use approved marine replacement parts that are
ignition protected. Using non-marine replacement parts may
cause fire and explosion that could result in death or serious
injury.
Engine Alignment
The engine uses a rubber spline hub to which the stern drive shaft is
attached. This alignment specication between the engine and stern
drive needs to checked periodically. It 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 special tools and procedures are required.
Engine Removal
In the event the engine or out-drive (sometimes referred to as stern
drive) requires major service where it needs to be removed, consult
your Regal dealer.
