Engine Oil
Pressure Gauge
(All Models)
Theengineoilpressuregaugeindicates
the pressure of the lubricating oil inside
the engine.The average pressure ranges
arebetweensix(6)poundspersquareinch
(PSI) at 1000 RPM to 40 PSI or more at
cruise-rangespeeds.Areadingofpressure
below 5 PSI at 1000 RPM may be caused
by a low oil level or other potentially serious prob-
lemsthatresultinlowoilpressure.If you experience
low oil pressure, stop your engine immediately and
check your oil level before operating again.
Do not continue to run the engine if the oil
pressure is low. If you do, the engine may be-
come so hot that it, or surrounding compo-
nents, could catch fire. You or others could
be burned and the boat seriously damaged.
Check your oil level and add an appropriate
amount of approved motor oil before operat-
ing again or have your boat serviced by your
local authorized dealer’s service department.
Note that damage to your engine from inap-
propriate oil levels can be costly to repair.
Such damage is not covered by your warranty.
Engine Synchronizing Switch
(MariStar 280 and X-80)
Thistwo-positionswitchallowstheenginestooperateinsynchronization.Do not en-
gage the switch unless the engines are running (for safety’s sake)! Prior to engaging
the synchronizing switch, ensure that you are in a large body of water. Avoid a tight
cove or narrow river, and docks, dams or other objects that may protrude into the body
of water. Be certain that there is a minimum of other vessels or trac as you will need
room to perform this procedure.
Engaging the engine synchronization functionality requires practice to master.
Because the boat will be in gear and will move during the process, even after
mastering the maneuver boat operators should synchronize engines only on
bodies of water of sufficient size to accomplish the maneuver without making
contact with other vessels or with inanimate objects, which could cause serious
bodily injury or significant damage to the boat.

MariStar 280, X-80
The port engine will have an RPM blip after the Sync switch is activated and
the throttle is moved to wide-open throttle on the MariStar 280 or X-80. If the
engine actually accelerates to wide-open throttle, then the Sync function did not
take control of the port engine. In this instance, reduce the speed and return to
Step 1.
 TheenginescanberunatdierentlevelsofthrottleBUTNOTWHENUTILIZING
THESyncFUNCTION!
 NOTE:DONOTengagetheEngineSynchronizingSwitchwhenloadingor
unloadingtheboatfromatrailerORwhendocking.Thesemaneuversrequirea
sensitive touch.
 TheMariStar280isequippedwithafour-levercontrol.(Seeimage.)
Step1: Startbothengines.Whileatidleandinneutral(shifternotmoved),
pressupontheSyncswitchtoturnthesynchronizationfunction
ON.
Step2: Pushtheport throttletowide-openthrottle.Therewillbeaslight
riseinRPMstotheengine(buttheboatshouldnotmoveforward
astheshiftingandthrottleresponsearecontrolledwithseparate
levers).WiththeSync switchON,however, theenginewill very
quicklyreturntoidle.
Step3: Usingthestarboard throttle,runtheboatuptothedesiredspeed.
Atthispoint,thesystemwillbeginfunctioningwithbothenginesin
sync.Thestarboardthrottlewillcontrolthespeedforbothenginesas
longasthesyncswitchisON.
Note: Before disengaging the sync functionality, move ALL levers back
to idle, beginning with the starboard throttle and shifter, and then the port
throttle and shifter. When the boat returns to idle, the engine synchroniz-
ing switch can be turned o. Failure to follow this procedure may result
in erratic handling of the boat, which may be beyond the boat operator’s
ability to handle.
