If the two engines’ speeds are not synchro-
nized while cruising, adjusting trim angle or
throttle can synchronize them.
If large differences in trim angle or throttle are
needed to synchronize the engines, consult
your Yamaha dealer for adjustments to the
throttle cables.

6Y8 Multifunction tachometers
The tachometer shows the engine revolutions
per minute. It has functions of trim meter, ad-
justing trolling speed, cooling water/engine
temperature display, battery voltage display,
total hour/trip hour display, oil pressure dis-
play, water detection alert, engine trouble
alert, and periodic maintenance notification.
If the cooling water pressure sensor is in-
stalled, the unit can also show the cooling
water pressure display. However, even if the
cooling water pressure sensor is not in-
stalled, the cooling water pressure display
can be shown by connecting an optional sen-
sor to the unit. For the optional sensor, con-
sult your Yamaha dealer. The tachometer unit
is available in round or square types. Check
your tachometer unit type.
