Breaking In Engine; Procedure For Hpdi Models - Yamaha VZ200 2019 Owner's Manual

Operation
motor greatly affects the water resistance. If
the mounting height is too high, cavitation
tends to occur, thus reducing the propulsion
and causing the engine to overheat. If the
mounting height is too low, the water resis-
tance will increase and thereby reduce en-
gine efficiency. Mount the outboard motor so
that the anti-cavitation plate is about 130 mm
(5 in.) above the bottom of the boat.
NOTE:
The optimum mounting height of the out-
G
board motor is affected by the boat and
motor combination and the desired use.
Test runs at different heights can help de-
termine the optimum mounting height.
Consult your Yamaha dealer or boat man-
ufacturer for further information on deter-
mining the proper mounting height.
For instructions on setting the trim angle of
G
the outboard motor, see page 34.

Breaking in engine

Your new engine requires a period of break-
in to allow mating surfaces of moving parts to
wear in evenly. Correct break-in will help en-
sure proper performance and longer engine
life.

could result in reduced engine life or
even severe engine damage.
Do not use premixed fuel in this engine

because it could cause carbon depos-
its on the fuel injector and engine trou-
ble.
Follow the instructions for break-in

carefully.
NOTE:
Leave the label pictured below on the top
cowling until the break-in procedure has
been completed. It may be removed after-
wards.

Procedure for HPDI models

Run the engine under load (in gear with a
propeller installed) as follows.
1. First 10 minutes:
Run the engine at the lowest possible
speed. A fast idle in neutral is best.
